baloo_file_extractor (5.42.0) using Qt 5.9.4

- What I was doing when the application crashed:

When logging in on my system I opened a crash log from kactivitymanagerd. I had some program running rogue (on memory) in the session before and to shut everything down by killing X11 und rebooting. Then I got the crash report of baloo.
