Application: kontact (5.2.3)

Qt Version: 5.7.0
Frameworks Version: 5.26.0
Operating System: Linux 4.1.31-30-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Quitting kontact with ctrl-q or via the menu

A lot of times kontact crashes when I quit the app. I can't think of anything else special that I'm doing in such a case, other than quitting the app...

The crash can be reproduced sometimes.

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