In 24.2:
emacs -Q
C-h f emacs-version RET
C-next
Answer "no" regarding executing the disabled command.
C-h f emacs-uptime RET
Click BACK in the help buffer.
Emacs again asks whether to execute the disabled command. It shouldn't ask the second time.

novice.el has the function disabled-command-function with the line:
      (help-setup-xref (list 'disabled-command-function cmd keys) nil)
The bug is fixed by deleting that line.
