title: jQuery $.session.set() suddenly undefined in Chrome
body: <p>Loaded libraries:</p>
  
  <pre><code>&lt;script type="text/javascript" src="/js/jquery-1.9.1.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="/js/jquery-ui.min.js"&gt;&lt;/script&gt;    
  &lt;script type="text/javascript" src='/js/jquery.session.js'&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="/js/functions.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>in Chrome: I had the following experience this morning:</p>
  
  <pre><code>$.session.set('auth',response.username);
  </code></pre>
  
  <p>throws Uncaught TypeError: Cannot read property 'set' of undefined</p>
  
  <p>I use:</p>
  
  <pre><code>if($.session.get('auth') !== undefined){
      $.getScript('script.js');
  }
  </code></pre>
  
  <p>and script.js does not get loaded
  this just started happening this morning in Chrome.
  Worked in other browsers - even chromium. 
  Ran upgrade (Ubuntu Trusty), 
  now chromium also not working. 
  Works in Chrome on Windows</p>
  
  <p>anyone else have their code break like this overnight?</p>
  
  <p>Update:  If I go incognito in Chrome, this issue disappears and my sites work correctly. Must be something in my settings for my google account?</p>
  
  <p>Anyone have a similar experience ever?</p>
