-- Information about the crash:
The crash report might be the same as in
https://bugs.kde.org/show_bug.cgi?id=490446 but this report is not about that.
I have Baloo disabled and when I boot my computer, I see it crashed like 10
times based on the number of icons in the tray.
I checked via the File Search control panel and using balooctl6 status.
There should not even be any index since I purged it.

The crash can be reproduced every time.

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