So I tried a different tactic and, noticing the error said the issue was
~dbus-session~ didn't exist, did this, instead:
> (arguments (list #:phases #~(modify-phases %standard-phases
> (add-before 'check 'start-xserver
> (lambda _
> ;; Tests require a running dbus-daemon.
> (system "dbus-daemon &")
> ;; For missing '/etc/machine-id'.
> (setenv "DBUS_FATAL_WARNINGS" "0"))))))
> (inputs (list python python-pygobject))
> (native-inputs (list xorg-server-for-tests))
This works much better and the 232 tests get run; most, even pass…except 4. The
output is thus:

It doesn't look like enough to clearly tell /why/ things failed (and looking
through the source of the particular failing tests isn't much clearer, for me,
unfortunately) but maybe someone's run across a similar experience, before,
that might indicate something to try.
