    cuisine-page: Add missing return sink for signal
    
    A signal with a return type other than G_TYPE_NONE expects “parameters
    to be passed to the signal, followed by a location for the return value”
    but the latter was not being supplied here. This can cause a segfault
    because the valist doesn’t contain the number of arguments GLib expects.
