Application: baloo_file (5.21.0)

Qt Version: 5.5.1
Operating System: Linux 4.1.27-27-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Baloo crashes after a while, no matter what I'm doing.

- Unusual behavior I noticed:
After a reboot, the desktop gets incrementally slower to the point of not being usable. Baloo takes more and more memory. After a long while, baloo crashes. Then the desktop becomes usable again.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
