Instead of thumbnails, the same icons with a crossed red circle

Instead of thumbnails, the same icons with a crossed red circle

Is it possible to somehow correct this display so that instead of signs there are real thumbnails?

Same problem here with Ristretto 0.8.2.
When there are some thumbnails for a folder (i.e. generated by Thunar) then Ristretto will display them. But Ristretto 0.8.2 will not start generation of thumbnails.

With Ristretto 0.8.0 this worked well.

Same here. Please see:

It appears that ristretto is not automatically generating thumbnails for these icons. If you open Thunar in the same directory, then open ristretto, the thumbnails are present.

I can confirm that this affects files in the home directory as well. Does ristretto create thumbnails, or is it maybe creating them in a legacy location?

Is this a problem with ristretto or tumbler? I can delete the caches at ~/.cache/thumbails and ~/thumbnails and it seems to work properly for a while but then stops again.
