Subject Re: [libcloud] Python 2.7 _to_images putheader failure, works on Python 2.6
Date Sun, 18 Jul 2010 11:57:14 GMT
Just before base.py calls httplib on line 433, it sets this header.

base.py: 426:
        headers.update({'Content-Length': len(data)})

Why that worked before, I don't know, but it shouldn't have and now doesn't.

that context. What header we're sending that isn't a string is another question.
