Bug 294183

Application: knotify4 (4.0)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.2.5-3.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I tried to remove a file from the system. (move to trash)
Because I tried with a user not having sufficient right to that file it did not work out. Knotify crashed...

The crash can be reproduced every time.

-- Backtrace:
Application: KNotify (knotify4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
