KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
KMix crashes randomly when some kind of audio stream is active (eg. SMPlayer, Flash, Amarok, etc.)

The crash can be reproduced some of the time.

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