Thanks for the test, I'll close the bug.

Not when the session bus is unavailable; this is a common use
case. Maybe a chaeck for the unavailability of the system bus. OTHOH, I
don't know whether there are collateral damages then.

You can check the availability yourself:

(dbus-ignore-errors (dbus-get-unique-name :system))
(dbus-ignore-errors (dbus-get-unique-name :session))

Both forms return nil, when the respective bus is not available.
