Sentry Crash Report:

Description Rainer Finke 2017-09-12 21:28:37 UTC 
Application: kmail (5.6.1)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed: Open Kmail in KDE Plasma Wayland, open other Wayland apps like Konsole and let it overlapp Kmail, on my AMD GPU Kmail flickering now in the overlapping area, go to Kmail again. Click the close button will result in a crash. 

- Unusual behavior I noticed: Kmail window is flickering. Cannot close the Kmail without a crash.

- Custom settings of the application: I run Kmail on Plasma Wayland nativly.

The crash can be reproduced every time.

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