I have a folder with an .xcf (GIMP) image, the image has a correct thumbnail in the nautilus window. When I copy (cut+paste) the image in the same folder the thumbnail is empty.
If I copy the image from a different folder the thumbnail shows the logo of GIMP.
In both cases the thumbnail is WRONG.
Doing the same with a .jpg or .png image the thumbnails are correct.
The same problem happens in Ubuntu 20.04 and 20.10
See the attached image
