+++ This bug was initially created as a clone of Bug #613216 +++

Description of problem:

The Python API can't send or receive a message with content-type "text/plain" if the content length is zero.

Version-Release number of selected component (if applicable):

How reproducible:

100%

Steps to Reproduce:

Use the following Python script:

>>> from qpid.messaging import Connection,Message
>>> conn = Connection("localhost")
>>> conn.open()
>>> sess = conn.session()
>>> xmt = sess.sender("amq.direct/key")
>>> m = Message()
>>> m.content_type = "text/plain"
>>> xmt.send(m)
  
Actual results:
