Bug 320149

Application: kded4 ($Id$)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-30-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
- Unusual behavior I noticed:

when I use external audio (headphone / boxes) it works, but the internal notebook-audio doesn't work in Kubuntu since a few days.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE-Dienst (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
