Application: baloo_file (5.6.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-18-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
Using KDE Control Module: File Search, I unchecked Enable File Search and clicked Apply.
I then re-checked Enable File Search and clicked Apply.
Then in terminal I ran balooctl status to check that reindexing was happening.
Crash occurs during reindexing.
Also, multiple catdoc crashes occured during reindexing.

The crash can be reproduced sometimes.

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