Application: kontact (4.4.6)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu 10.10

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

- Unusual behavior I noticed: prior to a reboot after which Kontact crasehes everytime it is opened the Plasma desktop environement was crashing if the machine was left idle for more than 5mins with Kontact running.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
