title: jQuery('select') error in Joomla 3.3 administator
body: <p>I'm running a Joomla! 3.3.0 installation and the front-end is fine, however I'm getting a <em>Uncaught TypeError: undefined is not a function</em> in the back end that is really annoying.</p>
  
  <p>When the error occurs, the "Search Tools" button doesn't work and I can't search a keyword, and the article/module edit page doesn't display any tabs.</p>
  
  <p><strong>This is really strange behavior since the error can disappear if I refresh the page a few times.</strong></p>
  
  <p>I realise this is most probably a Mootools/jQuery conflict, but in theory everything is the way it should be regarding noConflict being enabled.</p>
  
  <p>Here is the error I get:</p>
  
  <pre><code>Uncaught TypeError: undefined is not a function -&gt; index.php?option=com_content&amp;view=articles:206
  </code></pre>
  
  <p>The lines where the error is displayed:</p>
  
  <pre><code>jQuery(document).ready(function (){
                      jQuery('select').chosen({"disable_search_threshold":10,"allow_single_deselect":true,"placeholder_text_multiple":"Selecione alguma op\u00e7\u00e3o","placeholder_text_single":"Selecione uma op\u00e7\u00e3o","no_results_text":"Sem resultados correspondentes"});
                  });
  </code></pre>
  
  <p>I'm using Isis template whit no modifications
   for the administrator and this is how the .js files are being called in the <code>head</code>:</p>

  <p>I already tried plugins <a href="https://www.google.com.br/url?sa=t&amp;rct=j&amp;q=&amp;esrc=s&amp;source=web&amp;cd=1&amp;cad=rja&amp;uact=8&amp;ved=0CBwQFjAA&amp;url=http%3A%2F%2Fextensions.joomla.org%2Fextensions%2Fcore-enhancements%2Fperformance%2Fmootools%2F22236&amp;ei=CzTyU8mHDYvesASq8ICgCA&amp;usg=AFQjCNExMphbWiEenbfJq6JBiz8YZK0Ypg&amp;sig2=ASCxk-nhglNXnSZ8Ak6-Cg&amp;bvm=bv.73231344,d.cWc" rel="nofollow">Mootools Enabler/Disabler</a> and <a href="https://www.google.com.br/url?sa=t&amp;rct=j&amp;q=&amp;esrc=s&amp;source=web&amp;cd=1&amp;cad=rja&amp;uact=8&amp;ved=0CBwQFjAA&amp;url=http%3A%2F%2Fextensions.joomla.org%2Fextensions%2Fcore-enhancements%2Fperformance%2Fjquery-scripts%2F18327&amp;ei=KDTyU_6AEuLLsQTMy4K4CQ&amp;usg=AFQjCNGQSv_SNnp7naicn1FVBaTt14zh0w&amp;sig2=0EpjOWD7_kTvO8ehkkrZoA&amp;bvm=bv.73231344,d.cWc" rel="nofollow">jQuery Easy</a> with no luck, all they do is to break both front and back-end if I disable mootools or mootools-more.</p>
