   Maybe I am misunderstanding you, but in my case I want another value

The illegal value could only have been obtained by the user setting it
outside Custom, for instance with a setq in his .emacs.  The user can
not reliably correct the problem through Custom, he has to correct the
problem where the problem originated (probably .emacs).
