Description Chris 2017-09-26 13:46:50 UTC 
Application: kontact (5.5.2)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.4.85-22-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
This happens most mornings.  System is in a hibernating state overnight.  I start Kontact each mroning.  This crash happens and immedaiatly restarts Kontact without intervention on my part.  However the crash report shows up asking if I want to restart the application.  I cancel the restart and continue on with my day.  Given that this has been happening for the last three weeks I can only assume that there is something else wrong.  I'm just not tech savy enough to figure it out.

The crash can be reproduced every time.

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

Crash is in Qt5WebEngineCore. Without debug symbols, it is impossible to see the cause.
