Application: baloo_file (5.45.0)

Qt Version: 5.9.4
Frameworks Version: 5.45.0
Operating System: Linux 4.18.1-1.g2f1304f-default x86_64
Distribution: "openSUSE Leap 15.0"

-- Information about the crash:
- What I was doing when the application crashed:
working with kmail/kontact. 

- Unusual behavior I noticed:
sudden crash of baloo indexer. There are apparently also issues when filtering (do not know if related)

- Custom settings of the application:
The Kontact/kmail suite has been ported to postgres96 (as the mariadb had issues with this hardware asset (ironlake Lenovo 201) with indexing problems, LR errors etc. 
After the change these errors were seldom. However this is now the first time I see baloo crashing (at least that it pops up konqi, normally crashes silently).

The crash can be reproduced sometimes.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
