Bug 431836

Application: krusader (2.7.2 "Peace of Mind")
 (Compiled from sources)
Qt Version: 5.12.7
Frameworks Version: 5.71.0
Operating System: Linux 5.3.18-lp152.60-preempt x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.2"

-- Information about the crash:
- What I was doing when the application crashed:
I was copying and renaming video files (mp4) in a folder.
After telling KJrusader to load previews for each file, previews are shown in a snap, and then Krussader closes crashing.
It always happens whe loading preview images of this folder of videos.

The crash can be reproduced every time.

-- Backtrace:
Application: Krusader (krusader), signal: Segmentation fault
