Bug 299592

Application: kmix (4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: it occured a couple of times since I've installed kubuntu precise but now happened twice, the first just after logon

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMix (kmix), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
