title: WordPress admin area search not working
body: <p>Currently I have an installation of WordPress that is running a plugin called <a href="http://wordpress.org/plugins/types/" rel="nofollow">Types</a>. When I search for posts inside a custom post type I get no results at all. The URL string looks correct:</p>
  
  <pre><code>&amp;action=-1&amp;m=0&amp;seo_filter&amp;paged=1&amp;mode=list&amp;action2=-1
  </code></pre>
  
  <p>But it returns nothing.</p>
  
  <p>Additionally, when I remove <code>&amp;action=-1</code>, the search results show up correctly. I have tried disabling the plugin and it works correctly, however I have other sites using the same plugin and searching works on these.</p>
  
  <p>Does anyone have any ideas on how to fix this?</p>
