* no longer unset DBUS_SESSION_BUS_ADDRESS variable to prevent
gnome-session (and probably other DEs or programs, except of
Plasma) from launching a new D-Bus session, while systemd has
already launched its own. Unsetting it broke user systemd
services that use D-Bus (e.g. PulseAudio), because X uses
another D-Bus session (boo#1108549)
