Bug 296392

Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.2.10-3.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

KDE was starting up after logon. I just took fedora's update for kernel and kde. Now Kmix segfaults everytime at startup. Restarting Kmix from the degugging dialog panel is successful and it remains in the tray and apparently functions correctly.

The crash can be reproduced every time.

-- Backtrace:
Application: KMix (kmix), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
