Example file not working.

SUMMARY
Dolphin is not generating thumbnails for some PNGs, other software like Gwenview do, so it's unclear if the problem is specific to Dolphin or in kio-extras. If the thumbnail has been generated by another software, then it will display in dolphin, otherwise Dolphin will not generate one. I can attest to it by looking at the content of `~/.cache/thumbnails`.

STEPS TO REPRODUCE
Browse a folder with affected PNGs in Dolphin.

OBSERVED RESULT
It won't display thumbnails and `~/.cache/thumbnails` won't contain thumbnail for the affected files.

EXPECTED RESULT
A thumbnail should be generated in `~/.cache/thumbnails` and displayed in Dolphin.
