Description Magnus Anderson 2022-04-28 10:15:47 UTC 
SUMMARY
See title

STEPS TO REPRODUCE
1. Create or find an image/jxl file.
2. Open it using Okular

OBSERVED RESULT
Popup opens with
> Could not open file:///home/mag/Pictures/Screenshots/Screenshot_1.jxl. 
> Can not find a plugin which is able to handle the document being passed.
Printed to stdout says
> org.kde.okular.core: No plugin for mimetype '"image/jxl"'.

EXPECTED RESULT
Open the .jxl file

ADDITIONAL INFORMATION
kimageformats has a library that should be able to handle this, I think. It works in other KDE apps. So it should hopefully be a simple fix.
