Application: kontact (5.3.0 (QtWebEngine))

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.7.5-200.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

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

I can reproduces this bug by viewing an email and simply scrolling up and down until kontact crashes. Other kde applications (as in all I tried) work flawlessly.

The crash can be reproduced every time.

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