Application: kontact (4.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.8.0
Operating System: Linux 3.1.0-7.fc16.i686.PAE i686
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- What I was doing when the application crashed: Attempting to delete an e-mail. When I do anything (get new mail, delete mail, move an email to a diffrent folder), KMail seems to reload 30-40 old emails (ones which I've either deleted before or moved to other folders) back into the inbox. These then gradually disappear from the inbox again (although not always). Usually this just slows down KMail but it eventually does what I asked it, but some times it causes a crash.

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