bug#14063: 24.3; Reverting *Colors* buffer

[Jambunathan K]

M-x toggle-debug-on-error RET
M-x list-colors-display RET
M-x customize-variable list-colors-sort RET  <do whatever>
C-x b *Colors* RET
g

    Debugger entered--Lisp error: (void-function nil)
      nil()
      apply(nil nil)
      help-mode-revert-buffer(t nil)
      revert-buffer(t)
      call-interactively(revert-buffer nil nil)

I was hoping that the colors will be re-ordered.
