Application: baloo_file (5.6.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-21-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
I was starting libreoffice by typing <Alt>+<F2> "libreoffice --calc"
dialog appeared that baloo-file (I didn't request to start it) has ended.
Remark: I set /etc/security/limits.conf to "* hard as 8000000", as vlc tends to send the system down the drain allocating >>>16GB of RAM.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Baloo File (baloo_file), signal: Aborted
