JS error when fullPage is set to true and the title tag is missing

[Wiktor Walc]

Confirmed in FF 3.0.19.

When using CKEditor in fullPage mode, an error is thrown when <title> tag is not present.

Steps to reproduce:

• In Ajax sample add

  var config = {fullPage : true};
  

in createEditor() function.

• Open ajax sample, press "Create Editor".
• Press "Source" button or "Remove Editor".

Result:

element.children[0] is undefined
