Bug 291135

Application: kontact (4.8 rc2)
KDE Platform Version: 4.7.97 (4.8 RC2 (4.7.97)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

When opening an encrypted mail for the first time, kontact crashes.
After a restart I can read this mail without any problem. However if opening another
encrypted mail (coming from the same source and using the same encryption which is not secured by a password)
kontact crashes again with the same traceback.

This problem is still availabel in the current RC2 Version of Kmail for KDE 4.8

I am using Kubuntu beta build for KDE RC2 4.8 based on a 11.10 Kubuntu system.

The crash can be reproduced every time.

-- Backtrace:
