title: TypeError: e[h] is not a function
body: <p>I've been using jquery 1.6 with no problem. Today I switched to jquery 1.8 and suddenly I am getting this error when trying to submit a form:</p>
  
  <pre><code>TypeError: e[h] is not a function.
  </code></pre>
  
  <p>Form:</p>
  
  <pre><code>&lt;form method="post" action="login?login" name="login" id="login"&gt;
  &lt;input class="input" type="text" name="user_mail" id="user_mail" autocomplete="on" /&gt;
  &lt;input class="input" type="password" name="password" id="password" autocomplete="off" /&gt;
  &lt;a class="green_button" href="javascript:void(0)" id="login_button"&gt;Login&lt;/a&gt;
  &lt;input type="submit" name="login" id="submit" style="visibility:hidden" /&gt;
  &lt;/form&gt;
  &lt;script language="javascript"&gt;
  $("#login_button").click(function(){
      $("#login").submit();   
  });
  &lt;/script&gt;
  </code></pre>
  
  <p>Am I missing something?</p>
  
  <p>Thanks!</p>
