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:
Regards,
Markus
