Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
All programs were closed and the system was suspended to RAM. KMix frequently crashes when waking from suspend.

The crash can be reproduced some of the time.

-- Backtrace:
