Bug 292990

Application: kontact (4.8.0)
KDE Platform Version: 4.8.00 (4.8.0 (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.2.1-gentoo-r2 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
Resumed from hibernation, started Kontact, half a second after the window appeared, kontact went away and Dr.Konqi showed up.

This is the first time I had such a crash since I started using KDE-4.1. 

- I just tried to start kontact again, and a window informed me, that it would be running on another display. So I try again after sending this report.

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