Bug 495301

Description of problem:

I'm running rawhide very close to what's in Snapshot 1, and PulseAudio is now segfaulting within about five minutes or less of when I log in.  Once that happens, I hear no sound, and programs like pavucontrol cannot connect to the sound server.

The problem may very well be with ALSA or with the Intel sound driver, so feel free to reassign this but to one of those components if applicable.

Version-Release number of selected component (if applicable):

[jsmith@localhost ~]$ rpm -q pulseaudio alsa* kernel
pulseaudio-0.9.15-9.test8.fc11.i586
package alsa* is not installed
kernel-2.6.29.1-54.fc11.i586
alsa-lib-1.0.19-3.fc11.i586
alsa-plugins-pulseaudio-1.0.18-3.fc11.i586
alsa-utils-1.0.19-4.fc11.i586


How reproducible:

Always

Steps to Reproduce:
1. Log in (Probably isn't related, but the login sound is *very* broken up, and sounds awful)
2. Play sounds for a couple of minutes
3. Notice that pulseaudio is no longer running
4. Restart pulseaudio from the command-line
5. Watch it segfault
  
Actual results:

No audio after a couple of minutes

Expected results:

Audio playback should continue

When I restart pulseaudio from the command line, I almost immediately get the following output:
