Description Jeff Johnston

If the systemtap script for Call Graph isn't run properly (e.g. user is not part of stapdev group), the Call Graph view is empty.  Clicking on alternate views such as Tree View or Radial View causes a NullPointerException as the UI is not prepared with checks for an empty root.
