-- Information about the crash:
Kontact lately has been showing occasional crashes while remaining idle. I am not very sure for the cause though. The only delta is that I have hand installed kcaldav.

The crash can be reproduced some of the time.

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