title: Python Requests module ends up with strange redirection
body: <p>Making a GET request with the python module Requests ends up with strange url:</p>
  
  <pre><code>&gt;&gt;&gt; import requests
  &gt;&gt;&gt; r = requests.get("http://t.co/Uspy071j")
  &gt;&gt;&gt; print r.url
  "http://feeds.feedburner.com/%257Er/LesArdoises/%257E3/bD2JuJagz5I/roxino-cest-tout-vert.html?utm_source=twitterfeed&amp;utm_medium=twitter"
  </code></pre>
  
  <p>This url ends with an error 400. But using RestKit for the same url, the final_url return the correct value:</p>
  
  <pre><code>&gt;&gt;&gt; import restkit
  &gt;&gt;&gt; r = restkit.request("http://t.co/Uspy071j", follow_redirect=True)
  &gt;&gt;&gt; print r.final_url
  "http://lesardoises.com/6277/roxino-cest-tout-vert.html?utm_medium=twitter&amp;utm_source=twitterfeed"
  </code></pre>
  
  <p>What is the problem with Requests ?</p>
