Application: krunner (5.10.2)

Qt Version: 5.7.1
Frameworks Version: 5.35.0
Operating System: Linux 4.10.0-22-generic x86_64
Distribution: KDE neon User Edition 5.10

-- Information about the crash:
- What I was doing when the application crashed: Attempting to start KRunner, either through application launcher or Konsole

- Unusual behavior I noticed: It doesn't launch, also, unable to attach this bug report to existing copy under Wayland, Crash Reporting Assistant doesn't work as expected

- Custom settings of the application: Weston/Wayland

The crash can be reproduced every time.

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