Thunar launched under Wayland falls back to the default adwaita icon theme when it fails to load vectorized icons.
Steps to reproduce on Sway:
$ guix install dconf glib:bin papirus-icon-theme thunar
$ gsettings set org.gnome.desktop.interface icon-theme Papirus
$ GDK_BACKEND=wayland thunar
A workaround to this issue is to prepend 'LD_LIBRARY_PATH=$(guix build gdk-pixbuf+svg)/lib' to the thunar command.
