Sentry Crash Report:

Description stakanov.s 2017-08-26 10:42:53 UTC 
Application: kontact (5.5.2)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.79-19-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- What I was doing when the application crashed:
writing a new mail

- Unusual behavior I noticed:
The application crashed. Unfortunately this crash seem to be capable of triggering (from time to time) a complete system crash, immediate of all open users, with black screen without cursor and apparently with corruption of the akonadi cache. Actually the corruption of the cache has become the rule rather then the exeption. Normally I do not get a backtrace when the system goes down so violently. It then happens a little bit later while already writing an email. 
When writing the mail a strange window popped up, seemed like an empty copy of kontact, then the application crashed. 

- Custom settings of the application:

one pop account an one imap account set up. No other fancy things, but the user receives root mail from a maildir. Should not be involved.

The crash can be reproduced sometimes.

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