Re: pulseaudio causing crashing of applications

Hi folks,

Is anyone else seeing regular crashing of applications like pidgin, mplayer or xine caused by pulseaudio? Did anybody manage to get useful backtraces out of this?

I just had an issue with rhythmbox locking up while playing through pulseaudio. It locked only when I switched to VT1 where root was logged in, and it immediately stopped playing and froze. I've got the backtrace for all threads, but the top few are below. The rest is rather long so I won't post it yet. I haven't had rhythmbox do this before tonight.

Usually it will stop playing through the sink device (it is still trying to) until returning to the login that is running rhythmbox, but this time it actually froze and did not keep streaming to the sink.

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.
