-- Information about the crash:
System: KDE neon dev 6.6.80

After each system starting, I have error about baloo file extractor that crashes in loop. 
To stop this, I need to kill this processus and after I have no issue until the next restart.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Extractor (baloo_file_extractor), signal: Aborted
