Bug 298272

Application: kmix (4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Ubuntu precise (development branch)

-- Information about the crash:
I was messaging over gtalk with kopete. Prior to this I had watched a youtube video in firefox with flash. I had adjusted the volume only once between watching the video and instant messaging.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMix (kmix), signal: Segmentation fault
