Bug 271595

Application: knotify4 (4.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-29-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
The package closes unexpectedly almost every time ... if a pair of open packages, and try to work on any of the modules of Kontact, the package is closed unexpectedly. Is working very slow, what I can do? I'm relatively new to work with Kubuntu and I have had to learn to handle it alone and I still struggle to understand some things.

The crash can be reproduced some of the time.

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