Application: krunner (5.17.1)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-20-generic x86_64
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
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
