Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.9.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
- What I was doing when the application crashed:
Immediatly after login baloo_file_extractor crashes when all other tasks have become ready (taskbar, net, widgets ...)
Happens since upgrade from Deb 9 to Deb 10

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Extractor (baloo_file_extractor), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
