Application: baloo_file_extractor (5.22.0)

Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.4.10 x86_64
Distribution (Platform): Slackware Packages

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

Waiting for KDE to finish loading.

- Unusual behavior I noticed:

I noticed that the output of tty1 said that Baloo exited normally. But then some amount of time later, it crashes. This happens everytime after I start KDE.

- Custom settings of the application:

None that I know of.

The crash can be reproduced every time.

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