Sentry Crash Report:

Description davy+kdebugs 2017-04-03 15:43:29 UTC 
Application: kmail (5.3.0 (QtWebEngine))

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.49-16-default x86_64
Distribution (Platform): openSUSE RPMs

-- Information about the crash:
- Unusual behavior I noticed:
I didn't received mails since 2 days so I tried to restart the akonadi service with "akonadictl restart". After that Kmail took about 75% CPU load so I killed it and started again.

- What I was doing when the application crashed:
After reading one mail I clicked into another one and the application crashed.

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