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

KMail crashes when inline forwarding a GnuPG encrypted message (when forwarding the message as an attachment the message stays encrypted)

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
