Bug 276447

Application: knotify4 (4.0)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Hi, I just changed phon from vlc to gstreamer and knotify reported a crash.
I didn't realise a change also because I am not really sure what knotify is. :o)
Sincerely
T.Kijas

-- Backtrace:
Application: KNotify (knotify4), signal: Segmentation fault
