Re: GNOME no thumbnails?

I was looking on the internet for similar problem and found at least one 
other distro called clearlinux that reports a similar issue:

https://github.com/clearlinux/distribution/issues/701

I am not very knowlegeable about this, but checked it out a little on my 
own guixsd installation using GNOME desktop (I believe 3.28 as I updated 
recently).  It looks like thumbnails get generated by a thumbnailer 
program in GNOME (exactly how I am not sure), and get placed into the 
~/.cache/thumbnails directory.  Further, there are two subdirectories in 
that folder one called 'failed' and the other called 'normal'.  What I 
find is any time I add a picture file to my hard drive, a thumbnail file 
does get generated but is placed in the failed folder.  Looking at the 
failed thumbnail file however shows a blank image.

As a second test, I installed a picture viewer called geequi that lets 
me brows pictures by thumnails.  This program generated a bunch of 
thumnails and placed them into the ~/.cache/thumnails/normal folder.  
Then if I look at the same pictures in nautilus I can see the thumnails 
this time as the typical small picture next to the file name.

So it appears that existing normal thumnails display in nautilus once 
they are generated, but the problem is they are not being automatically 
generated through nautilus for new picture files as one would expect.

Should this be filed as a bug in guixsd or is it a gnome problem or is 
it something that needs to be configured somhow?
