Bug 266455

Application: knotify4 (4.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.37-999-generic i686
Distribution: Ubuntu 10.10

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

Listening to Pandora, Movie Player, and Google Talk alternatively causes Google Talk sound to stop. To fix this, I run sudo /sbin/alsa force-reload which causes the crash.

The crash can be reproduced every time.

-- Backtrace:
Application: KNotify (knotify4), signal: Aborted
