My first guess is that you have customized `TeX-expand-list', but
looking at the custom variable list you provieded, it doesn't seem so.

Then I suspect that older installation of AUCTeX interferes with the
latest one. Don't you have AUCTeX<13 somewhere? You can usually check by
examining the value of `load-path'.

Or you may still be using an emacs session invoked _before_ upgrading
AUCTeX. In that case, please restart your emacs session. In general,
files loaded before upgrade can conflict with the files loaded after
upgrade.
