Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.6.0-tp1
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I've format the hard drive recently. When I configured Kmail for the first time, the application crashes while checking the mail accounts. If I run Kontact again, Kmail automatically checks the mail at the begining (so I configured) and crashes again. I can't keep Kontact open for more than 2-3 seconds.

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