Application that crashed: kontact
Version of the application: 4.3.0
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30.5-43.fc11.x86_64 x86_64
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
Kmail sometimes crashes when I manually delete mails from my imap account. Until now I haven't figured out when this likely will happen so I cannot reproduce it (eg. if kmail is sth. doing in the background).
