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

Hello!
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.

Testing Bionic, Ristretto 0.8.2.
Same here. Please see: http://i.imgur.com/7EAoxRm.png

brainwash, from the Xubuntu Bugs team found that reverting https://git.xfce.org/apps/ristretto/commit/?id=69b7459957427aed16caddb699c5b496dfb6deee seems to resolve this issue. I have tested and confirmed. Can we go ahead and do this to restore thumbnail generation?

Igor, can you revert the commit mentioned above, and maybe follow up with a new release? Lots of translations and a few fixes since 0.8.3. Thanks!

Sean, thanks for pointing out the problematic commit!

But... Does memory leak present now? Should we re-open Bug #12034?
