Bug 284521

Application: kontact (4.7.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

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

I have a folder with encrypted messages.

When opening this folder the first time after logging in or when opening it with a new encrypted message it crashes.

After restarting kmail (but without logging off) i can read the encrypted mail.

The crash can be reproduced some of the time.

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