Bug 312830

Application: kontact (4.9.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.4
Operating System: Linux 3.6.10-4.fc18.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- 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
Using host libthread_db library "/lib64/libthread_db.so.1".
