bug#573: 23.0.60; ns-save-preferences: Wrong type argument: numberp

[Cezar Halmagean <cezar@mixandgo.com>]

I have compiled nextstep emacs from cvs today (10 min ago) and when I  
try to select the "Save Options" option from the menu I get this error:

ns-save-preferences: Wrong type argument: numberp, (internal-border- 
width . 2)
