Bug 225880

Application that crashed: kontact
Version of the application: 4.3.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-1-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
OS was under load as many resource hungry kde applications were run. kontact was idle and it crashed. Not sure if it can be reproduced again.

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