emacs-xwidgets not working (gdk-pixbuf-error-quark) also no icons

[Moisés Simón]

Any help to fix this issue is gretly appreciated.

So I have never managed to get icons to work in my guix system. Not even with a 
basic reconfigure with desktop.tmpl and I think now that this is because I have 
broken my system somehow.

Now I have detected that I can't launch emacs-xwidgets it throws the following 
error:
https://paste.debian.net/1265886/

Note I have run it in container to make sure my system or profile configuration 
is not messing with it, but I get the same error running in it on my profile. 
Installing it on system gave same results.

Thanks for this magnificent system and package manager.
