Are the systemd-ui & systemd out of sync on this machine?

Sure the DBus signature of that method was changed in 2012... but
reverting that commit _now_ will induce yet another API break.

Note that imho the current JobNew/JobRemoved signals are imho incomplete -

See:
http://lists.freedesktop.org/archives/systemd-devel/2015-January/026928.html

But it is again too late to break the DBus api again. See comments on
that thread.
