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 2.6.31.6-166.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

What I was doing when the application crashed:
Kmail crash randomly when filtering mail on one of my imap accounts. This happens most the time on first start/check, but even when I manually apply all filter to the rest of the mails in the inbox. A few crashes later I could filter all mails and then kmail seems to stable for the rest of the day.
