I've filed a bug against httplib2 and included a patch.

The easiest way to fix this is probably to tell Launchpad to remove "Cookie" from the Accept header when serving web service requests. That's easier than fixing httplib2 in the short run, and removing 'Cookie' should be enough to get this to work.
