Playing around I found out, that it doesn't work if there are the lines
  \context { \RemoveEmptyStaffContext 
%     \context { \AncientRemoveEmptyStaffContext 
     \override VerticalAxisGroup #'remove-first = ##t
  }
  }
in the layout block.
If these lines are commented out %
everything fine.
Try the following test-file.

\paper {
        #(set-paper-size "a4")
        top-margin = 0.5\cm
        bottom-margin = 2\cm
        left-margin = 2\cm
        right-margin = 2\cm 
        ragged-last-bottom = ##t
}
