Step 3. Describe the issue

Quickshell based wallpaper changer missing thumbs for filenames with spaces.

Also probably thumbnail generation is not working or something wierd happening with iteroping NTFS, but until thumbs are generated by dolphin those files don't show thumbnails too.

Logs not very helpful
