The problem is that ConfigParser.ConfigParser is an old style class. It 
is in the standard library, so I have no clue why. For old style 
classes, you should directly call the ancestor class method.
For new style classes it works just fine:


class ConfigParser(object):
    def add_section(self, section):
        print section, "in ",self.__class__.__name__

class MyConfig(ConfigParser):
    def add_section(self, section):
        super(MyConfig, self).add_section(section)

m = MyConfig()
m.add_section("blah")


The output:

blah in  MyConfig
