Bug 423610

Application: krunner (5.19.80)

Qt Version: 5.14.2
Frameworks Version: 5.72.0
Operating System: Linux 4.15.0-108-generic x86_64
Windowing system: Wayland
Distribution: KDE neon Unstable Edition

-- Information about the crash:
- What I was doing when the application crashed:
Launched KRunner, started typing. This started with the latest updates of neon unstable. Unfortunately it's fully reproducable. Using the search in application launcher widget does not crash.

The crash can be reproduced every time.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
