I'm not sure exactly when unref became safe; I would suggest just never
unref'ing if the version is before 1.0

The daemon will clean up when your app exits or disconnects, so the
unref is purely about freeing the DBusConnection object in your own
process. This connection will be kept around by libdbus until it's
disconnected in any case, even if you unref. So the unref only matters
if the connection disconnects. For the session bus connection, normally
the connection only disconnects if the user logs out. So basically on
logout, if your app keeps running after logout, you would leak some
memory. If your app exits on logout anyway (which is the default), then
the unref doesn't matter.
