I saw this issue as well updating to urllib3 in nova image-show

 nova/image/glance.py's show() method

following is not getting properties

image = self._client.call(context, version, 'get', image_id)

glance api returns image properties with same case as

• X-Image-Meta-Checksum →d41d8cd98f00b204e9800998ecf8427e
• X-Image-Meta-Container_format →bare
• X-Image-Meta-Created_at →2015-08-13T19:12:26.235339
• X-Image-Meta-Deleted →False
• X-Image-Meta-Disk_format →raw
• X-Image-Meta-Id →03dc7a38-6b1b-4464-b2b5-7e517a8bbbcc
• X-Image-Meta-Is_public →True, etc...

So when glance client calls the api, request/adapters.py
build_response() , should convert them into case insensitive like

x-image-meta-checksum, but this is not happening with new urllib3
response object.

They are not converted as expected by the glance client. and then glance
client treats this as no properties retrieved for the image. In fact the
glance api is returning proper response. But because of this conversion
failure, its throwing attribute error.
