Bug 373422

Application: baloo_file (5.18.0)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-53-generic i686
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I just logged in. I did NOT ask to run Baloo...
- Unusual behavior I noticed:
I installed KUbuntu this WE - since then, Baloo start and crashes each time i log in

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
