Bug 323916

Application: kmail (4.11)
KDE Platform Version: 4.11.00
Qt Version: 4.8.4
Operating System: Linux 3.8.0-29-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
1. I accidentially selected a pgp encrypted mail and kmail asked me for passphrase
2. As I didn't actually wanted to decrpyt it, I hit cancel.
3. For some reason I was asked again for passphrase, hit cancel again
4. Kmail crashed

The crash can be reproduced every time.

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