I don't understand this - the docs you quoted indicate that
connection_open() will not register with the bus, which is correct,
because a DBusConnection does not have to be a connection to a bus.
So having the C++ wrapper for connection_open register isn't right either.
dbus_bus_get() does register with the bus, since it knows it's a bus.
In C++ I'd expect that to be wrapped separately and as a static or
factory method, rather than as a constructor.
