Well, that's true. It probably a deadlock of some kind. Create an empty file
~/.config/banshee-1/always-debug, restart Banshee, and and the next time it
hangs, run "killall -SIGQUIT banshee". After that attach ~/.config/banshee-1/log
here.

That being said, even if Banshee didn't deadlock, the situation wouldn't be much
better. Thing is, Banshee plays media files from that mount. If the mount hangs,
then it follows that your playback is going to hang, or in this case, based on
your logs, writing metadata changes back to file (presumably play counts). And
because it's hanging in the middle of a system call, you're also not going to be
able to quit and restart, because at least one thread will be completely stuck
(and unkillable).

Title:
  Cannot restart banshee after crash

Status in “banshee” package in Ubuntu:
  Invalid

Bug description:
  If banshee crashes the sound/audio system menu still shows it as
  available but nothing happens if I click on it. With ps I can see a
  defunct banshee process that cannot be removed. If I try to run
  banshee from the command line nothing happens. Restarting gdm and/or
  unity also has no effect. As far as I can tell there is now no way to
  start banshee short of rebooting which is annoying. Does anyone know
  how I can start banshee without closing everything down and rebooting?
  Perhaps there is some part of Ubuntu that controls the sound menu and
  I can restart that? I was hoping it was part of gdm or unity but
  restarting them didn't help.

  Description:	Ubuntu 13.04
  Release:	13.04
  but I have seen the same behaviour in 12.04
