Does this recipe work for you? It is a limited use case, because you
have to manage your own session bus address, instead of using `:session'.

If you need a more general solution, because you use libraries which
depend on the `:session' bus, you might try to postpone the load of dbus.el
to the emacsclient call, after setting $DBUS_SESSION_BUS_ADDRESS properly.

Best regards, Michael.
