Application: baloo_file (5.18.0)

Qt Version: 5.5.1
Operating System: Linux 4.8.0-52-generic x86_64
Distribution: Ubuntu 16.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I wa susing Opera and Chorme
- Unusual behavior I noticed:
I'ts the second time that baloo restarts, the worst part is that it happens and then my laptop rebots.

The crash can be reproduced sometimes.

-- Backtrace:
