It seems the difference between my two test machines is that one one I had logged in to Unity 7 previously, and that left gnome-session-binary running. After a reboot to kill all systemd --user units, konsole now hangs on both test machines.
It looks like this problem is in konsole, which requires gnome-session to be running in order to function normally.
