Bug 300192

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:
Selecting an email while it gets loaded in the review area.
- Unusual behavior I noticed:
It always crashed after looking through a few mails.
This behavior is new in Kontact of Kubuntu 12.04.

The crash can be reproduced every time.

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