Bug 292040

Application: kmail (4.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.1.9-1.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

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

1) Select a GPG encrypted message; a dialog requesting the password should pop up
2) Press cancel in that dialog
3) Warning box appears saying that the password was invalid (???) and two options are presented, Cancel or Retry.
4) Without clicking either Cancel or Retry, select a different message in the message window; nothing will happen, but the selection is possible.
5) Click Cancel in the popup dialog.
6) Kmail crashes.

The crash can be reproduced every time.

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