I guess this is either a bug in cus-edit+ (wrongly assuming any of
customized-value, saved-value, standard-value can be `eval'ed in any
buffer), or it's a bug in Auctex (for putting a customized-value,
saved-value, or standard-value that can't be `eval'ed in any buffer).

Does M-x customize-option TeX-auto-global RET give a similar error?
