-- Information about the crash:
When kmail crashed, I had clicked on an email I wanted to see. The interface froze up and I decided to browse some web sites. Then the crash handler popped up. About 5 minutes had ellapsed from the time I clicked on an email until the crash occurred. I do have filters that send email to the trash. So, I don't know if that had anything to do with a crash.

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