So, what you're saying is that running the full XFCE stack with the
plain xfce from guix is currently broken?  I think that deserves to be
called a bug, but it'd also have a fairly simple patch of adding
adwaita-icon-theme, no?

SVG handling is in a somewhat rough spot currently.  There's some GNOME
packages on current master, that have broken icons due to gdk-
pixbuf+svg being severely out of date.  These are for the most part
known (at least the core GNOME ones like evince) and will probably
vanish with the c-u-f merge.  Consequently, I don't think it makes
sense to report broken icons due to this reason on master; one would
have to look into the c-u-f situation. 

Note that SVG is anyway broken for those not on x86_64, because that's
the only platform that has Rust.  Maybe there's an effort to derustify
SVG handling in Gdk similar to how there's an open merge request to use
duktape in polkit.  If not, I did suggest elsewhere to pre-render SVGs
with other tools like inkscape.
