Application: baloo_file_extractor (5.20.0)

Qt Version: 5.5.1
Operating System: Linux 4.4.5 x86_64
Distribution (Platform): Slackware Packages

-- Information about the crash:
- What I was doing when the application crashed:
I had just started KDE with "startx".

- Unusual behavior I noticed:
None

- Custom settings of the application:
In the past, baloo hasn't been working, so I'm thinking my system needs to be reindexed. I can't even search for anything in the KDE menu, either, due to baloo not having finished indexing in the past before crashing.

The crash can be reproduced every time.

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