Bug 428939

Application: krunner (5.19.5)

Qt Version: 5.15.1
Frameworks Version: 5.73.0
Operating System: Linux 5.8.18-300.fc33.x86_64 x86_64
Windowing system: X11
Distribution: "Fedora release 33 (Thirty Three)"

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

I had opened krunner via Alt+Space.  Crash occurs immediately when I start to type.

Note: While these symptoms are the same as other bug reports, my backtrace is different.

The crash can be reproduced every time.

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