Title:
  f-spot hangs on exit.

Status in “f-spot” package in Ubuntu:
  Invalid
Status in “mono” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: mono

  Description:	Ubuntu 8.04
  Release:	8.04
  Package: f-spot: /usr/bin/f-spot

  
  To reproduce. Upgraded installation. Start f-spot (either from the command line or a menu). Wait for the initial window to appear. Click on File -> Exit. The application hangs. stracing it shows it stuck in a futex wait. Looks like a mono locking issue to me.

  100% reproducible. This is a blocker bug for me to upgrade all my
  desktop machines (f-spot is my primary photo manager).

  strace output when in hung state (endlessly loops):

  Let me know what more you need to track this down. Note this is *NOT*
  the same as the previously reported "f-spot crashes on exit" segv bugs
  reported, this is a hang.
