Application: apper (0.7.1)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.8.0
Operating System: Linux 3.1.4-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Installing adobe flash player, the application just looping of 'Waiting service to start', when forced to close, the application pops out the crash handler.

The crash can be reproduced every time.

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