title: Android No view found for ID in FragmentManager
body: <p>Can someone more familiar with <code>Fragment</code> details that I am tell what is causing this error? It is occurring for a number of users, but I don't have any info on exactly what they're doing when it occurs and I am unable to recreate anything on my own device.</p>
  
  <p>Here is the stack trace. It appears to be happening when the fragment is being popped from the backstack -- is this correct? Any other clues?</p>
  
  <pre><code>java.lang.IllegalArgumentException: No view found for id 0x7f0c006b for fragment AncestorNavFrag
