Sentry Crash Report:

Description Thomas Berger 2011-02-19 16:23:49 UTC 
Application: knotify4 (4.0)
KDE Platform Version: 4.6.00 (4.6.0) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I send some mails via kontact. Because of the silly Exchange 2007, i am connected to, each send message is followed by three notifications about setting UID and some other. 

If there are to many notifications to fast, knotify would die.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KNotify (knotify4), signal: Aborted
