I think I found a small bug in
        twistedcaldav/mail.py

When providing no icons,
1114 iconPath = self.getIconPath(details, canceled, language=language)
will set iconPath to "None" and
1280 if os.path.exists(iconPath) and htmlTemplate.find("cid: %(iconName)s") != -1:
will fail with such an error message:
2009-04-17 14:23:27+0200 [-] [mailgateway] exceptions.TypeError: coercing to Unicode: need string or buffer, NoneType found

I catched that case by extending the test:
1280 if iconPath != None and os.path.exists(iconPath) and htmlTemplate.find("cid:%(iconName)s") != -1:
