Subject: GNOME Files: No file thumbnails

GNOME Files (nautilus) does not display thumbnails of files like images, videos, and other files that usually have thumbnails. This makes it hard to browse large directories of multimedia files. 

## Steps to reproduce

1. Start GNOME Files.
2. Make sure that  "GNOME Files → Preferences → Search & Preview → Thumbnails" is active ("Files on this computer" is the option selected in my case for files less than 10 MB).
3. Browse to a directory that contains images.

## Unexpected result

All images are represented by the same icon, so you can only differentiate them by file name (when the files are not generated by devices like cameras).

## Expected result

You can see thumbnails of all images so you can browse them by their content, not only by their file name.

## System information

GNOME 3.32.2
