Bug 417491

Application: baloo_file_extractor (5.55.0)

Qt Version: 5.9.7
Frameworks Version: 5.55.0
Operating System: Linux 4.12.14-lp151.28.36-default x86_64
Distribution (Platform): openSUSE RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I started my system. opened Dolphin and from a HTML file stored in dolphin opened firefox browser. A bit later Baloo closed suddenly and I got a message. 
Yesterday I started my system, opened Dolphin and from there opened Gwenview and Showfoto. While these programmes were running Baloo kept on crashing.
This problem only started after yesterdays (Tuesday 11 februari) update of Open Suse. Before that it didn't happen.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Baloo extraheerder uit bestanden (baloo_file_extractor), signal: Segmentation fault
