Bug 294597

Application: knotify4 (4.0)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.2.6-7-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

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

I was restoring KDE from suspend inside a VMware Player 4.0.1 virtual machine. The VM restores the state and KNotify crashes before the desktop becomes available. The crash repeats each time I restore from suspend. in the VM.

The crash can be reproduced some of the time.

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