Application: gwenview (19.12.3)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-91-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:

1. I opened a .png image which I would be ok with to disclose with gwenview through dolphin or in the terminal by calling `gwenview IMG_1197.png`
2. Gwenview started 
3. Gwenview crashed immediatly.

- What I can tell as well:

This issue exists for image files exported by/from darktable including `.png` and `.jpg` formats. Their thumbnail is show in Dolphin, other image viewers are able to display them without any problem. This is very likely related to #44112 but that posts title is very specific (I would even argue offtopic) and seem to refer to JPEG-images only.

The crash can be reproduced every time.
