[mod_python] Problems with ZODB / modpython

Hi,

I'm trying to install a program that needs mod_python and ZODB. The
program is not running, so I tried to connect to the database through
this script:

from ZODB import FileStorage, DB

def index(req, **params):
        storage = FileStorage.FileStorage('mydatabase.fs')
        db = DB(storage)
        connection = db.open()
        root = connection.root()
        return TestPage().getHTML()

And I received the error below.
Does anybody know how to fix it?

Thanks

Thiago
