Problem with writing RESTful Google App Engine Code

So after I used middleware to make browsers work with RESTful URLs in GAE, I started to write more than simple little methods and I'm trying to write a test application. Upon doing so, I ran into a defect with how request parameters are returned for a PUT request. To be fair, this is more of a problem with webob than with GAE, but I hope that this gets fixed because my attempts at monkey patching the problem have not worked out too well.
