Sentry Crash Report:

Description Andreas Mahel 2016-09-16 11:13:19 UTC 
Application: kontact (5.3.0 (QtWebEngine))

Qt Version: 5.6.1
Frameworks Version: 5.25.0
Operating System: Linux 4.7.3-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
There is one specific mail in my mail folders. On opening this mail KMail will crash.

The same happens when:
 - KMail, preview pane enabled => selecting the mail in the message list
 - KMail, preview pane disabled => selecting the mail in the message list works, opening the mail will crash KMail
 - Akonadiconsole, browser => selecting the message in the akonadicontrol browser will crash Akonadiconsole

I have the message both in a local folder from a pop account, as well as in a IMAP folder => the crash happens either way.

I could also reproduce the issue in a freshly set up Opensuse Tumbleweed system (default KDE desktop setup).

KMail Version 5.3.0 (QtWebEngine)
Using:
KDE Frameworks 5.25.0
Qt 5.6.1 (built against 5.6.1)
The xcb windowing system

The crash can be reproduced every time.

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