This also occurs if you pass --always to upstart-dbus-bridge, so I don't think it's got anything to do with upstart events/jobs.
I suspect this is a bug in unity-panel-service. Specifically at unity/services/panel-service.c:753. It's using dbus_connection_open() when it should be using g_dbus_connection_new_...() to get the mainloop integration. Without this, upstart hangs onto the dbus messages as they aren't being read.
