Application: systemsettings (1.0)
KDE Platform Version: 4.8.00 (4.8.0
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I tried to get ioquake3 running with pulseaudio without distortion had to force reload alsa a few times and restart pulseaudio (which runs in user mode) - phonon isnt able to react to the changes and crashes.

The crash can be reproduced some of the time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Aborted
