Sorry, this got rather lost. I'll try to refresh the patch I upstreamed
soon (it has some known issues due to being older than the dbus-user-session
code paths that actually landed).

Downstream: https://bugs.debian.org/835887

Upstream: https://bugzilla.gnome.org/show_bug.cgi?id=694472

What needs to happen, at a minimum, before the patch on the upstream bug
can land: https://bugzilla.gnome.org/show_bug.cgi?id=694472#c8
