Application: baloo_file (5.15.0)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-27-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed: 
I booted up and logged in, a few seconds later I got the Baloo crash report. 
This is repeatable.

This install is a few days old but with a re used /home.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
