Comment 8 for bug 293164

If I stick the OAuth query variables in the query string, they go through and the client key is recognized. There is no decoding problem, but a problem getting the data to be extracted from the form. I ran an experiment on the string that gets sent through the server. It is processed correctly by OAuthRequest._split_header. So the problem is that the Authorization header isn't being picked up by Launchpad. And it only happens on staging.
