Bug 355371

Application: baloo_file (5.15.0)

Qt Version: 5.5.0
Operating System: Linux 4.1.12-1-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
About half of the time when a new file is created by a program  (it doesn't seem to matter which one), in my home directory I recive a segfault from Baloo.  It don't happen if I create a new file by hand, that I've noticed, but sometimes happens when I copy a file from on directoy to another.

This may not be a KDE issue, as I have used plasma 4.4 with Feddora and Kubunu as well and I only experience this issue with OpenSuse.

The crash can be reproduced sometimes.

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