Summary: Dolphin creates thumbnails for thumbnails when opening
~/.cache/thumbnails
Classification: Applications
Product: dolphin
Version First 26.08.1
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED

DESCRIPTION
According to FDO thumbnail managing specification
(https://specifications.freedesktop.org/thumbnail/latest-single/), the
directory with thumbnails has the following structure:
- $XDG_CACHE_HOME/thumbnails/
- $XDG_CACHE_HOME/thumbnails/normal
- $XDG_CACHE_HOME/thumbnails/large/
- $XDG_CACHE_HOME/thumbnails/x-large/
- $XDG_CACHE_HOME/thumbnails/xx-large/
- $XDG_CACHE_HOME/thumbnails/fail/
According to the specification,
> You must not create/save thumbnails for any files you will find in these
> directories.
However, when folder previews are enabled (they are enabled by default), and
you open ~/.cache/thumbnails, Dolphin creates thumbnails for some of the
thumbnails.
STEPS TO REPRODUCE
1. Make sure you have folder previews enabled in Dolphin (Configure Dolphin >
Interface > Previews > Folders).
2. Remove all files in ~/.cache/thumbnails.
3. Save a picture in your home directory, open the directory to make Dolphin
create a thumbnail.
4. Open ~/.cache/thumbnails.
OBSERVED RESULT
Dolphin created a thumbnail for the thumbnail of your picture in one of
subdirectories named above. This happens every time you open
~/.cache/thumbnails.
EXPECTED RESULT
Dolphin should not create thumbnails for any files in ~/.cache/thumbnails or
subdirectories.
