Comment 9 for bug 1657452

Appending a few comments that sigmavirus had on bug #1657459:

"I filed https://github.com/Pylons/webob/issues/307 although I doubt anything will come of it upstream. If anything, that might help others."

"Another facet of this for Glance seems to be related to the PR in WebOb that broke other projects: http://paste.openstack.org/show/595699/ I suspect this is due to us returning `webob.exc.HTTPNoContent()`. It looks like our gzip middleware expects there to be a content-type but that's no longer auto-generated for us."
