Sentry Crash Report:

Description Kwanza.Pili 2019-01-15 20:46:32 UTC 
Application: kmail (5.10.0)
 (Compiled from sources)
Qt Version: 5.12.0
Frameworks Version: 5.54.0
Operating System: Linux 4.12.14-lp150.12.28-default x86_64
Distribution: "openSUSE Leap 15.0"

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

I simply closed the application (kmail).  I suspect this might be a problem with qtwebengine. I had problems with konqueror crashing as well, and filed a bug report with QT (which was fixed).
 I use: kmail-18.12.0, plama5-5.14.4, and qt-2.12.0 .

The crash can be reproduced every time.

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