title: invalid tumblr head, duplicated doctype, strange javascript
body: <p>i got a problem with my tumblr blogs. There is some piece of javascript and a duplicated doctype in my two different themes, which i can't remove on the custom settings area or on the theme markup settings. </p>
  
  <p>The support couldn't help.</p>
  
  <p>The really bad thing on this: the page is damn invalid, so you can't visit it in some browser, especially on Linux.</p>
  
  <p>The wrong code:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;&lt;script&gt;!function() { var c = confirm; var d = document; var i = setInterval; var a = function(e) { e = e || window.event; var t = e.target || e.srcElement; if (t.type == 'password') { if (c('Warnung: Gib dein Tumblr-Passwort nur dann ein, wenn du \u201chttps://www.tumblr.com/login\u201d\x0ain der Adresszeile deines Browsers siehst.\x0a\x0aAu\u00dferdem sollte dort ein gr\u00fcnes \u201cTumblr, Inc.\u201d-Logo zu sehen sein.\x0a\x0aSpammer und andere Strolche benutzen gef\u00e4lschte Formulare, um an Passw\u00f6rter zu kommen.\x0a\x0aTumblr wird dich niemals bitten, dich vom Blog eines Users aus einzuloggen.\x0a\x0aWillst du ganz sicher fortfahren?')) { a = function() {}; } else { t.value = ""; return false; } } }; i(function() { if (typeof d.addEventListener != 'undefined') d.addEventListener('keypress', a, false)}, 0); }();&lt;/script&gt;&lt;!DOCTYPE html&gt;
  </code></pre>
