Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
I launched Firefox woth Krunner, it was successful, but Krunner crashed.
After a few retry, the bug stopped happening
- Unusual behavior I noticed:
The application launcher doesn't work, although it might be totally unrelated

The crash can be reproduced every time.

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