Well, I think Richie meant it should be:

    def __getattr__(self, attributeName):
        '''On-demand loading of the message text.'''

        if attributeName in ('hdrtxt', 'payload'):
            return self.__dict__[attributeName]
        except KeyError:
            raise AttributeError, attributeName

That is, __getattr__ is called when hdrtxt or payload are accessed but not
yet initialized.  All other accesses (or if self.load() fails somehow)
should raise AttributeError.  See Corpus.py 1.3.
