Application: baloo_file (5.18.0)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-45-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

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

At least three times baloo has failed on kde init. The first fail was when I killed the kde application.

The crash can be reproduced sometimes.

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