Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-45-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Just initiate the normal plasma session after endind the wayland session.

- Unusual behavior I noticed:
It crashes and most of the time I cannot generate bactracing in plasma session.

- Custom settings of the application:
None change on baloo_file_extractor or db mechanisms was done.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Aborted
