I have posted several backtraces [1].  I don't know if its PA related info or 
not really.

I had posted several of them to a bug [2] tonight with xulrunner/firefox 
crashing but there are striking similarities between the xulrunner crashes and 
rhythmbox.  I don't know if this is related to pulseaudio (not likely) but it 
could definitely be causing issues in most of those threaded apps.

After galeon crashed once, as soon as I quit galeon (was attached in gdb) 
rhythmbox crashed as well right afterward.

The rhythmbox bt I posted in the last email is there, and another one that 
occurred after galeon crashed.  The CPU spins 100% as soon as this happens, and 
it just looks like there could be some threading issues going on with the latest 
rawhide changes.  I thought it was xulrunner alone, but it looks likely that the 
rhythmbox crash was related.  I tried but could not duplicate the timing of this 
crash (galeon -> rhythmbox).

When rhythmbox has crashed, opening it again and just starting it playing has 
fixed things, its not as if the pulse server is dead.  I have already installed 
the new gstreamer-0.10.17-1 in koji, but I believe those two backtraces were 
just before I installed it.

Most of the debuginfo is missing, but I'll be trying to remedy that and see if 
these crashes keep happening.
