I've seen one of the symptoms you describe:

  The GUI key popping up Accept Key dialogs with Yes and No options but no
  text.  It was only when we canceled that we saw the error message about
  there being an old, conflicting key.  

I used vi to remove the entry in my hosts file.   But that blank pop up
that just asks: YES NO 
and nothing else ??   Selecting YES didn't seem to do anything.  NO at least
popped up an error message in another window.
