Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.2.0-20-generic x86_64
Distribution: Ubuntu precise (development branch)

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

Kmix crashes Amarok _or_ Google Talk plugin get started. Perhaps DragonPlayer also might crash it, I do not remember clearly.

I am sorry if this report is a duplicate. I installed the debug package but it cannot resolve the line where the crash happens.

The crash can be reproduced some of the time.

-- Backtrace:
