Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0

-- Information about the crash:
- What I was doing when the application crashed:
I was using firefox; kmail and other applications were active as well.
However it had already crashed at sometime during the session because I had to manually start it.

The crash can be reproduced some of the time.

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