title: Failed to create the part's controls
body: <p>I get a null pointer exception opening about half of the android XML files in my layout directory. There seems to be no pattern to why some files open and some files don't.</p>
  
  <p>I upgraded eclipse to Juno. Re-installed all the plugins (ADT), re-installed the android SDK. I brought in my old workspace and adjusted my projects to point at the new android SDK.</p>
  
  <p>Stack</p>
