Application: baloo_file (5.18.0)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-21-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
I was hoping this problem would disappear when upgrading to 16.04 but it does not. Usually Baloo would crash immediately when I turned my computer on. Now it takes a few minutes after I log in.

The crash can be reproduced every time.

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