Application: baloo_file (5.62.0)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-23-generic x86_64
Distribution: Ubuntu 19.10

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

system restart, this is repeatable, its happened for years across 3 kubuntu versions, I even did a complete reinstall from scratch, 14 months ago, and it still happens.

- Unusual behavior I noticed:

baloo indexer is reported to have crashed

- Custom settings of the application:

None, I've never used baloo, and don't use KDE search.

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".
