Bug 405893

Application: baloo_file (5.56.0)

Qt Version: 5.11.3
Frameworks Version: 5.56.0
Operating System: Linux 5.0.4-050004-generic x86_64
Distribution: Ubuntu Disco Dingo (development branch)

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

I deleted all baloo files/directories in my homedir (for a clean re-indexing) and logged in.
Running "balooctl start" also crashes immediately.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
