title: phantom error "error parsing XML: unbound prefix"
body: <p>The error "error parsing XML: unbound prefix" shows up on my main layout: main.xml when I first open Eclipse. To make the error go away, all I  have to do is make a modification to the file, then undo it, then hit save (have to make a change in order to be able to save file and thus trigger the new syntax check). </p>
  
  <p>My environment is: </p>
  
  <pre><code>Fedora Eclipse Platform
  Version: 3.4.2
  Based on build id:  20090211-1700
  </code></pre>
  
  <p>My target is Android API level 5. </p>
  
  <p>The first time I saw the error I spent a long time trying to track down "the problem" but later realized there isn't really a problem, it's just a phantom error. </p>

  <p>Who should I report this to? </p>
