output from dieing PA

Description of problem:
PA playing to remote PA dies shortly after starting pavucontrol. Sometimes it's CPU time exceeded, sometimes assertion like in summary.
I tried generating annotated sources after oprofile, but it didn't work claiming that debuginfo is not installed (which is not true, pulseaudio-debuginfo is installed).

Version-Release number of selected component (if applicable):
pulseaudio-0.9.15-10.fc11.x86_64
pavucontrol-0.9.8-1.fc11.x86_64
kernel-2.6.29.1-70.fc11.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Have totem playing to remote PA.
2. Start pavucontrol

  
Actual results:
Sound stops, applications displays info about broken connection and PA daemon is dead.


Expected results:
Smooth playback
