i did a slightly different fix in tools.py, starting on line 537:

                if attachments:
                    result =
mail.send_mail(sender=self.settings.sender, to=to,
                                            subject=subject,
body=text, html=html,
                                            attachments=attachments)
                else:
                    # fix starts here
                    if html:
                        result =
mail.send_mail(sender=self.settings.sender, to=to,
                                                subject=subject,
body=text, html=html)
                    else:
                        result =
mail.send_mail(sender=self.settings.sender, to=to,
                                                subject=subject,
body=text)

massimo, can something like this be put into trunk? i was able to fix
all of my own emails in code, but the one causing the error for me is
the standard verification email which seems to have ceased to work for
gae.

thanks,

matt
