Application: kontact (5.0.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-18-generic x86_64
Distribution: Ubuntu 15.10

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

I tried to forward an email. Selected a mail, pressed "Forward" -> "Inline" and Kmail crashed. The same behaviour was encountered with other options of the "Forward". Not sure if it is relevant, but the mail was an invitation to a meeting from MS Outlook and contained attachments. Furthermore, my other folder (connected with Gmail) was syncing folders at that moment (all those times).

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
