Bug 299242

Application: kontact (4.8.2)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Trying to open mail that had been automatically moved to different folder via filter.

- Custom settings of the application:
Custom filter settings to sort mail into different folders when new mail arrives.

-Note:
This problem happens several times a day but is not consistent. After Kmail crashes, it still attempts to fetch new mail in the background every X minutes.  If the new mail is to be filtered into another folder, Kmail displays one of several error messages, then loads several copies of the message into the other folder.  If the new mail stays in the main inbox, there is no error.

The crash can be reproduced some of the time.

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