bug#39117: GNOME Files: No file thumbnails

[Jonathan Brielmaier via Bug reports for GNU Guix]

I'm running nautilus@42.2 and it shows thumbnails for at least JPEG and
PNG images.

This is on a rather recent Guix System installation:
```
$ LANG=en guix system describe
Generation 10   Jan 07 2024 16:46:14    (current)
[...]

      branch: master
      commit: 9816a5371663396bc092eb359222635e5675b174
```

So can we close this issue?
