Bug 409958

Application: baloo_file_extractor (5.60.0)

Qt Version: 5.12.3
Frameworks Version: 5.60.0
Operating System: Linux 4.18.0-25-generic x86_64
Distribution: Ubuntu 18.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:

First login to the freshly booted KDE Neon machine.

Baloo crashed on startup.

System was updated with 'pkcon refresh && pkcon update' and crashed again after a full restart.

The crash can be reproduced every time.

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