This bug is due to <http://bugs.gnu.org/22175>, which appears to be
fixed by the patch below (I tested it in a VM.)

Could you confirm that it works for you?  You would need to apply the
patch with ‘patch -p1 bugfix.patch’ in a fresh checkout of Guix, and to
run ‘./configure && make && ./pre-inst-env guix system reconfigure’ from
there.

TIA,
Ludo’.
