Application: plasmashell (5.11.2)

Qt Version: 5.9.2
Frameworks Version: 5.39.0
Operating System: Linux 4.13.8-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was testing Plasma under wayland (I normally use it on Xorg, without any relevant issue).
Plasma crashes almost every time that I click out of the Application menu (not the application launcher - the application menu), after scrolling a bit into it and spawning a few cascade menus. 
Plasma becomes blac, crashes, and gets respawned some time after its crash.

- Unusual behavior I noticed:
Plasma shell crashes under Wayland, when clicking out of the application menu.

- Custom settings of the application:
I use the Application Menu under Wayland, instead of the Application Launcher.

The crash can be reproduced every time.

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