Sentry Crash Report:

Description Andrej Dundovic 2009-12-28 10:59:54 UTC 
Application that crashed: knotify4
Version of the application: 4.0
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.9-174.fc12.i686 i686

What I was doing when the application crashed:
Steps:
1. suspend to RAM (from KDE Kickoff)
2. wake up from suspend
3. unlock screen (enter password)
-> Knotify4 crash

Sometimes Knotify4 doesn't crash but takes all CPU time (100%) after waking up from suspend for few minutes.

OS: Fedora 12 installed from KDE LiveCD
Comp: Acer Aspire One ZG5

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

This could be bug 206713 (I can't be sure as the situations are a bit different). Thanks
Comment 2 Myriam Schweingruber 2010-02-10 00:13:50 UTC 
The backtrace is identical to bug 196320, just a different situation that triggers it.
