bug#52044: Various Program Settings not Saving and Icons not Recognized

[Jaft via Bug reports for GNU Guix]

So my original plan of using gdk-pixbuf+svg somewhat can't work as it's not 
longer a viable package (at least, my attempts to upgrade runs into an error 
that says so); per commit feab09f72abc6d6eec16a1b8d27c231c747c0e00, it seems 
the idea is to use librsvg in place of it but, as I noticed in one of my 
previous E-mails, librsvg doesn't seem to have SVGs work (leastwise, in the 
programs I originally was using gdk-pixbuf+svg with as I'm not sure how to test 
in a way that's agnostic; I tried swapping gdk-pixbuf+svg with librsvg in the 
packages I'd been testing against and, while that allowed me to reisntall the 
programs without error, viewnior, thunar, and rofi are all back to not being 
able to render any icons which are SVGs).
