You need to handle both cases. Check the type of the argument to determine 
which one is called. For the one you aren't interested in, just call the base 
implementation...

    def updateSearch(self, arg):
        if not isinstance(arg, QString):
            superclass.updateSearch(self, arg):
        else:
            do_your_thing()
