While making any request to v1.1 of the api, an empty 400 is returned. Another user has a similar issue on SO (http://stackoverflow.com/questions/28133384/twitter-api-app-only-authorization-error). All requests are made using Application-only Authentication.
Primary problem is that there is no error response. I’ve seen similar post on the forums, but no answers
