Description Max Kanat-Alexander 2007-11-29 19:48:07 UTC 
I'm using Rhythmbox on Fedora 8, and it locks up about twice a day. Here's a stack trace of the last lock-up, with full debugging symbols installed:

For what it's worth:

* PulseAudio doesn't crash or lock up at the same time, that I know of.
* Rhythmbox still responds to a SIGTERM, I don't have to SIGKILL it.
* The icon appears in the system tray for a little while, but half of it is 
  cut off. Eventually it disappears.

This is a bug in gst-pulse.  Apparently you can't emit error messages from an audio sink reset method, because the base audio sink's state change function holds the object lock, and building the error message involves taking that same lock.
