Application: plasmashell (5.16.2)

Qt Version: 5.12.4
Frameworks Version: 5.59.0
Operating System: Linux 5.1.15-arch1-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Trying to open the plasma menu (either the application launcher or the application menu)

- Unusual behavior I noticed:
Cascading popup menus become slower and laggier, until everything crashes (sometimes). If the system doesn't crash, the application menu doesn't open anymore (the button becomes highlighed, but doesn't do anything. Same with 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".
