Found the answer in this excellent blob post:
http://john-smith.appspot.com/app-engine--what-the-docs-dont-tell-you-about-processing-inbound-mail
This is how to decode an email attachment for GAE inbound mail:
for attach in mail_message.attachments:
filename, encoded_data = attach
data = encoded_data.payload
if encoded_data.encoding:
data = data.decode(encoded_data.encoding)
