You just might want to call g_signal_handler_disconnect from whithin the signal handler. You'll have to stash the handler ID you get from g_signal_connect() somewhere accessible from the handler (for example in the user data struct). OTOH, g_signal_add_emission_hook() seems to be the function made for you :) In an emission hook function you just return FALSE if you want the hook to be removed. You'll have to check whether your particular signal accepts emission hooks, though.
