Description sedrubal 2017-01-14 02:30:26 UTC 
Application: kontact (5.3.3 (QtWebEngine))

Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.8.16-300.fc25.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- Custom settings of the application:

I started KDE with wayland and tried to start kontact from application launcher or krunner. But it always crashed. Starting `kontact` from a terminal seems to work.

The crash can be reproduced every time.

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

Comment 1 Christoph Feck 2017-01-19 13:31:50 UTC 
Crash is in QtWebEngine with OpenGL support, either caused by the EGL wayland integration, the i965 drivers, or Qt's web engine.

I suggest to report this issue directly to Qt developers via https://bugreports.qt.io/
