Application: plasmashell (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.18.6-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

When using Kicker (not sure if that's the correct name; the application launcher with menu structure similar to KDE 3), I navigated two levels down (top level > category > subcategory > items). When I now move my mouse outside the menu, the menus stay visible. When my cursor returns to the top level, hovering another category, Plasma crashes.

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".
