Qt Version: 5.12.1
Frameworks Version: 5.56.0
Operating System: Linux 4.19.28-1-lts x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
logged in to a session after boot
within the previous session baloo also crashed without visible cause

- Custom settings of the application:
I do not consider this to be relevant but if it is, I don't want to waste anybodys time by not mentioning that I replaced kwin with i3.

-- Backtrace:
Application: Datei-Extraktion für Baloo (baloo_file_extractor), signal: Aborted
