Description itsef-admin 2012-02-22 13:02:47 UTC 
Application: kontact (4.7.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
1) Select an encrypted mail in the message list
2) OpeGPG passphrase dialogue pops up
3) Leave dialogue open and click on another mail
4) Now, cancel passphrase dialogue
=> CRASH

The crash can be reproduced every time.

(In reply to comment #1)

Additional information:

- This is a very longstanding bug and was originally reported by us against the Kolab version of KMail1/Kontact e35 - see https://roundup.kolab.org/issue4524 for more info.

- We are not using any GPG/gpgagent/whatever set-up, as that is not allowed by policy. Encrypted mails are never decrypted here, but transferred to a separate network.

- The attached mail is a generic sample mail which works to reproduce the problem.

- Kontact does NOT crash when I close (cancel) the passphrase dialogue *without* having clicked anywhere else - in that case, the encrypted mail will just be displayed.
