Application: kontact (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
   Deleting message from inbox, while KMail started an automatic mail check at the same time
- Unusual behavior I noticed:
   None. Everything fine up until I deleted the message.
- Custom settings of the application:
   Incoming new mail is filtered and forwarded to different folders.  This seems to have caused problems before.

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