Comment 3 for bug 1361134

Yao Zheng,

The previous modifications were just to redirect this bug to the correct project (python-glanceclient is the most likely culprit at this point).

It looks like somehow the _request method in glanceclient.common.http is ending up being passed a header that has None as the value. Is there any way you can reproduce this problem but edit the line right above
> headers = self.encode_headers(headers)
to print out or log the headers, and include the results here?
