index idx_path already exists

I have just installed Ubuntu 9.1 and am having the problem when I run

sudo mt-daapd -f

[general]

#
# web_root (required)
#
# Location of the admin web pages.
#
# If you installed from .RPM, .deb, or tarball with –prefix=/usr, then
# this is correct.
#
# If you installed from tarball without –prefix=/usr, then the correct
# path is probably /usr/local/share/mt-daapd/admin-root.
#

web_root = /usr/share/mt-daapd/admin-root

#
# port (required)
#
# What port to listen on. It is possible to use a different
# port, but this is the default iTunes port
#

port = 3689

#
# admin_pw (required)
#
# This is the password to the administrative pages
#

admin_pw = senior09

#
# db_type (required)
#
# This is what kind of backend database to store the song
# info in. Valid choices are “sqlite” and “sqlite3”.
#

db_type = sqlite3

#
# db_parms
#
# This is any extra information the db needs to connect.
# in the case of sqlite and sqlite3, this is the name
# of the directory to store the database in
#
# If you installed from RPM or .deb, this path likely already
# exists. If not, then you must create it. The directory itself
# must be writable by the “runas” user.
#

db_parms = /var/cache/mt-daapd

#
# mp3_dir (required)
#
# Location of the mp3 files to share. Note that because the
# files are stored in the database by inode, these must be
# in the same physical filesystem.
#

mp3_dir = /home/media/music

#
# servername (required)
#
# This is both the name of the server as advertised
# via rendezvous, and the name of the database
# exported via DAAP. Also know as “What shows up in iTunes”.
#

servername = 1904

#
# runas (required)
#
# This is the user to drop privs to if running as
# root. If mt-daapd is not started as root, this
# configuration option is ignored. Notice that this
# must be specified whether the server is running
# as root or not.
#
# This is also ignored on Windows.
#

runas = jp9gz

#
# password (optional)
#
# This is the password required to listen to MP3 files
# i.e. the password that iTunes prompts for
#

#password =

#
# extensions (optional)
#
# These are the file extensions that the daap server will
# try to index and serve. By default, it only indexes and
# serves .mp3 files. It can also server .m4a and .m4p files,
# and just about any other files, really. Unfortunately, while
# it can *attempt* to serve other files (.ogg?), iTunes won’t
# play them. Perhaps this would be useful on Linux with
# Rhythmbox, once it understands daap. (hurry up!)
#
# Failing that, one can use server-side conversion to transcode
# non-standard (.ogg, .flac) music to wav on the server side.
# See the ssc_* options below.
#
# To be able to index .ogg files, you’ll need to have configured
# with –enable-oggvorbis. For .flac, –enable-flac, for .mpc,
# –enable-musepack.
#

extensions = .mp3,.m4a,.m4p

#
# ssc_codectypes (optional)
#
# List of codectypes for files that the daap server should
# perform internal format conversion and present to clients
# as WAV files. The file extensions that these codectypes correspond
# to must also be present in ‘extensions’
# configuration value, or files are not probed in the first
# place.
#
# Valid codectypes:
#
# mp4a – for AAC (.aac, .mp4, .m4a, .m4p)
# mpeg – for mp3
# wav – for wav
# wma – for wma
# ogg – for ogg
# flac – for flac (.flac, .fla)
# mpc for musepack (.mpc, .mpp, .mp+)
# alac for alac (.m4a)
#

# Not needed because ffmpeg is enabled (all file types transcoded to wav.
# If this behavior is undesired, see the [plugins] section and disable it,
# or selectively disable codecs below with the never_transcode option.)
# -joshk
# ssc_codectypes = ogg,flac,alac

# never_transcode (optional)
# Comma separated list of formats to never transcode. (Nothing by default)
# never_transcode = ogg

#
# ssc_prog (optional)
#
# Program that is used in server side format conversion.
# Program must accept following command line syntax:
# ssc_prog filename offset length …
# Parameter filename is the real name of the file that is
# to be converted and streamed, offset is number of bytes
# that are skipped from the beginning of the _output_ file
# before streaming is started, length is length of the song
# in seconds (or zero). All other possible arguments must
# be ignored. The resulting wav file (or the rest of
# the file after initial seek) is written to the standard
# output by the ssc_prog program. This is typically
# a script that is a front end for different conversion tools
# handling different formats.
#

# ssc_prog = /usr/bin/mt-daapd-ssc.sh

#
# logfile (optional)
#
# This is the file to log to. If this is not configured,
# then it will log to the syslog.
#
# Not that the -d switch will control the log verbosity.
# By default, it runs at log level 1. Log level 9 will churn
# out scads of useless debugging information. Values in between
# will vary the amount of logging you get. However, you must log
# to a file to see this debugging information (debug information will
# not appear in syslog.)
#

#logfile = /var/log/mt-daapd.log

#
# rescan_interval
#
# How often to check the file system to see if any mp3 files
# have been added or removed.
#
# if not specified, the default is 0, which disables background scanning.
#
# If background rescanning is disabled, a scan can still be forced from the
# “status” page of the administrative web interface
#
# Setting a rescan_interval lower than the time it takes to rescan
# won’t hurt anything, it will just waste CPU, and make connect times
# to the daap server longer.
#
#

rescan_interval = 3600

# always_scan
#
# The default behavior is not not do background rescans of the
# filesystem unless there are clients connected. The thought is to
# allow the drives to spin down unless they are in use. This might be
# of more importance in IDE drives that aren’t designed to be run
# 24×7. Forcing a scan through the web interface will always work
# though, even if no users are connected.

# always_scan = 0

#
# scan_type
#
#
# This sets how aggressively mp3 files should be scanned to determine
# file length. There are three values:
#
# 0 (Normal)
# Just scan the first mp3 frame to try and calculate size. This will
# be accurate for most files, but VBR files without an Xing tag will
# probably have wildly inaccurate file times. This is the default.
#
# 1 (Aggressive)
# This checks the bitrates of 10 frames in the middle of the song.
# This will still be inaccurate for VBR files without an Xing tag,
# but they probably won’t be quite as inaccurate as 0. This takes
# more time, obviously, although the time hit will only happen the
# first time you scan a particular file.
#
# 2 (Painfully aggressive)
# This walks through the entire song, counting the number of frames.
# This should result in accurate song times, but will take the most
# time. Again, this will only have to be incurred the first time
# the file is indexed.
#

#
# compress
#
# Whether to use gzip content-encoding when transferring playlists etc.
# This was contributed as a patch by Ciamac Moallemi just prior to the 0.2.1
# release, and as such, hasn’t gotten as much testing as other features.
#
# This feature should substantially speed up transfers of large databases
# and playlists.
#
# It will eventually default to 1, but currently it defaults to 0.
#

Any suggestions?
