Application: kontact (4.7.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

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

Right-click on an SMIME encrypted mail.
Select Forward -> Inline... .
[KMail crashes]
After restarting Kontact or KMail, an empty Composer window appears additionally to the application window.


- What SMIME encrypted mails produced this error:

* Most encrypted mails can be forwarded inline without problems, but the "bad" ones always create the segfault.

* The "bad" ones seem to be created with a recent version of MS Outlook 2007, all other mails seem to work perfectly.

* Forwarding of signed (not encrypted) or plaintext mails received from Outlook 2007 also works without errors.

* Forwarding of encrypted Outlook 2010 mails also works without errors.

* There seems to be a second issue where attachments in encrypted mails created with Outlook 2007 can not be opened. It might be related (because of the recent version of Outlook 2007 as sender) but i found no bug reports concerning this. Also, attachments are irrelevant to reproduce this "Forward -> Inline..." bug.

The crash can be reproduced every time.
