Application: kontact (4.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.1.1-gentoo x86_64
Distribution: "Gentoo Base System release 2.0.3"

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

I just closed Kontact because my mail folders somehow did not sync any longer. I waited about a minute, then started Kontact again. It crashed instantly...

The crash can be reproduced some of the time.

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