             Summary: Python "buffer" type in Message body should map to AMQP 
bytes[] encoding
                 Key: PROTON-1325
                 URL: https://issues.apache.org/jira/browse/PROTON-1325
             Project: Qpid Proton
          Issue Type: Bug
          Components: python-binding
    Affects Versions: 0.14.0
            Reporter: Brian Bouterse


If I try to send a message like this it fails due to an encoding error.

from proton import Message
Message(body=buffer('asdf'))

If you try to send this and fail to specify an encoding, you will get an 
encoding traceback like this one.
