Well, I wasn’t able to browse with iTunes either.
With iTunes (6.0.2) I got “shared library not accessible
for unknown reason (-3250)”. But after this mt-daapd doesn’t
get stuck and web interface keeps working.
Maybe the difference is that iTunes shuts down the connection
bluntly but Roku tries to shut it down nicely and keeps
hanging. This is however just a wind guess.
Anyways, something is wrong.
The weird thing is that Roku works nicely while the initial
is going on if the server is started with -s and scan started
via web interface.
