Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
on startup, kontact crashes before any interaction. I have 2 imap mail resources and use akonadi for contacts. Additionally, I have 4 google calendars (read-only, mapped as network .ics file).

I *think* this also happened once in a while before switching to akonadi, but I cannot say for sure. Additionally, I get an error message saying that kmail (or kontact?) cannot talk with klauncher for some reason, but this might be independent of this problem.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
The current source language is "auto; currently c".
