Bug 292638

Application: systemsettings (1.0)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.1.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:

Attempting to configure sound devices. I opened multimedia tab of sytemsettings for phonon and it crashed. 
I had just edited my /etc/asound.conf and saved it, Phonon had queried me if I would like to forget a device. I clicked yes.
Phonon immediately crashes through terminal command as well. 
Also crashes when systemsettings is run as root, kdesudo.
I will attempt a restart of my machine to see if it can be temporarily fixed.

The crash can be reproduced every time.

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