Yes, that’s better.  I pushed two commits:

  gnu: libxfce4ui: Do not propagate gtk+-2.
  (b8d3a000efca885180277358caa3c4fe604168a5)

  gnu: xfce: Build union instead of propagating inputs.
  (c860d6ef235b47ec8181fbf390e0b42fbc95dcfe)

With these two commits I can install xfce without problems.

I just tried to update my GuixSD system to commit
c57b56722f6c167c5a285f47802047de85a356ae on master.  "guix system build"
failed with the following error:
