Unable to download object as stream using download_object_as_stream method for OpenStack Swift.

HI,

I am unable to download object as stream from the OpenStack Swift storage as when i try to run the "download_object_as_stream" method by passing object_instance and chunk size, on Python 2.7 environment, and when i try to iterate the generator object returned it is giving me an error message as:
"HttpLibResponseProxy' object has no attribute 'next'".

And when i change the execution environment to Python 3.6, it is giving me the error as:
"'HttpLibResponseProxy' object is not an iterator"

And as per my understanding the read_in_chunk callback method is throwing this exception, but don't know the reason exactly, whether it a problem with execution environment or anything else.

Please try to provide a solution/patch/approach to resolve this issue.

Regads,
