I've just explained it in my mail to Andy. As it was discussed some time ago with GLib developers, we introduced two new bus types called "user" (G_BUS_TYPE_USER) and "machine" (G_BUS_TYPE_MACHINE). At this moment, these are only available on GLib devel branch, so I should replace G_BUS_TYPE_USER with G_BUS_TYPE_SESSION before I posted my benchmark apps - sorry for that.
