Description freggy1 2008-04-30 17:12:41 UTC 
Now that bug #512226 has been fixed, I encountered this new deadlock with Mandriva's Rhythmbox which has the patch for bu #512226 applied.

To reproduce:
- Start Rhythmbox, crossfade back-end enabled
- Double click on song in library to start playing
- Press pause
- Press play
- Double click again on the same song

Rhythmbox deadlocks, while instead it should restart playing the same song from the beginning.

backtrace:
(gdb) thread apply all bt

+ Trace 196536

.. doesn't look like the patch has been applied.
