Bug 277415

Application: knotify4 (4.0)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 3"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.8-0.2-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
Crashes at times when system sounds would be played (I am not hearing these).  Specifically, I get crashes at KDE startup; also when power adapter is disconnected or reconnected.

I have recently installed XBMC Media centre and UPnP tools (Both of which appear to be working correctly).  The issue appeared subsequently.

The crash can be reproduced every time.

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