title: Xcode 6 crash on UI debug
body: <p>I'm using Xcode 6.0.1 on Mavericks and experiencing crash every time I try to inspect UI and:</p>
  
  <ol>
  <li>unfold the view hierarchy</li>
  <li>rotate the 3D inspection view</li>
  </ol>
  
  <p>But it's not just crash. It literally restarts my Macbook Pro.</p>
