Hi guys!
I have encountered a crash inside dbus library when sending message to
receiver that is absent on the bus. Crash happens because
dbus_message_iter_init API is called with NULL for its first argument.
The attached patch fixes this crash. Could you please apply it to the
main egg repository.

Thanks,
