Bug 314107

Application: apper (0.8.0)
KDE Platform Version: 4.9.5
Qt Version: 4.8.4
Operating System: Linux 3.7.4-204.fc18.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

1. Opened Apper
2. Typed 'kdbg' into search field
3. Pressed 'Enter'

After that, application unexpectedly crashed. I suppose this may be related to #296426 , as two most top stack frames are that same.

The crash does not seem to be reproducible.

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