Bug 303629

Application: kmail (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I click on the line with the offending e-mail.
Kmail crashes, every time.
I cannot provide a sample, unless I get help, since the program crashes as soon as I touch it...

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
