Oh, I don't mean that I used another branch; I saw it got merged to master (I 
believe) so I just did a guix pull and then guix upgrade. I'm still using 
stable. Sorry about the confusion!

I just checked and it does; I was going off of the package formation in Guix 
but, checking the listed dependencies on the rofi GitHub page 
(https://github.com/davatorium/rofi/blob/next/INSTALL.md#external-libraries), 
it does list gdk-pixbuf as one so, perhaps, it makes more sense to build with 
that instead of librsvg.

I had assumed the package inputs for rofi were already accurate and, if 
gdk-pixbuf doesn't have SVG support while gdk-pixbuf+svg does, it seemed 
plausible that gdk-pixbuf+svg would be the preferred package for librsvg as 
librsvg is dealing with SVGs, perhaps part of the reason for SVG icons not 
getting rendered in applications like Thunar, XFCE, etc. (that being said, I'm 
unfamiliar with the librsvg code so, perhaps, this assumption of how the 
gdk-pixbuf dependency is being used is incorrect, on my part).

In any case, librsvg is not listed as a dependency for rofi while gdk-pixbuf is 
and swapping librsvg for gdk-pixbuf+svg in the rofi package still seemed to 
build it alright (and render SVGs) so, at least directly for rofi, directly 
using dgk-pixbuf+svg would still solve the SVG issue for it.
