I don't know what you are doing wrong. It works just fine for me:

[code]
from ConfigParser import SafeConfigParser
from StringIO import StringIO

class MyConfigParser(SafeConfigParser):
    def optionxform(self, optionstr):
        print "Called the modified version of the class"
        return optionstr

def main():
    contents = StringIO("""
[Section1]
Foo=Bar
Bar=Baz
Spam=Eggs
[Section2]
Hello=World
""")

    raw_parser = SafeConfigParser()
    raw_parser.readfp(contents)
    print "Using SafeConfigParser Section1"
    for item in raw_parser.items("Section1"):
        print item
    print "Using SafeConfigParser Section2"
    for item in raw_parser.items("Section2"):
        print item

    contents.seek(0)
    my_parser = MyConfigParser()
    my_parser.readfp(contents)
    print
    print "Using MyConfigParser Section1"
    for item in my_parser.items("Section1"):
        print item
    print "Using MyConfigParser Section2"
    for item in my_parser.items("Section2"):
        print item

if __name__ == "__main__":
    main()
[/code]

Produces the output:

Using SafeConfigParser Section1
('foo', 'Bar')
('bar', 'Baz')
('spam', 'Eggs')
Using SafeConfigParser Section2
('hello', 'World')
Called the modified version of the class
Called the modified version of the class
Called the modified version of the class
Called the modified version of the class

Using MyConfigParser Section1
('Foo', 'Bar')
('Bar', 'Baz')
('Spam', 'Eggs')
Using MyConfigParser Section2
('Hello', 'World')
