-- Information about the crash:
After re-installing my laptop with Fedora 40 and putting my /home backup back  (excluding the baloo folder under .local/share and excluding baloo config under .config, as I epxected that to be problematic) baloo started re-indexing and crashed a couple of dozen times in a short row.
I hope the backtrace is somewhat helpful in finding the root cause, else feel free to get back to me if you need further information.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo-Dateiinfosammler (baloo_file_extractor), signal: Segmentation fault
