caused an error, see backtrace:
Debugger entered--Lisp error: (wrong-type-argument stringp nil)

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?

The cus-edit+.el code for this is essentially the same as the
cus-edit.el code for commands such as `customize-rogue'.  And
such commands are intended (of course) to be usable with any
buffer current.

Similarly, there is nothing in a non-interactive function such
as `custom-variable-state' that says that it should be called
only from a particular buffer or set of buffers.

It is true that such functions use `eval', and there is a risk
that the property value is a sexp whose evaluation raises an error.

Perhaps a usage note is called for in the doc of such functions?

Indeed, the OP was able to reproduce the error with the normal customize
interface (see above), so the problem isn't with cus-edit+.

AFAICT, the problem is that auctex uses a standard-value for
Tex-auto-global that includes (file-name-directory load-file-name) as
part of the expression.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

Hm...  this is the definition of that variable:

(defcustom TeX-auto-global
    (if (file-writable-p "/usr/local/var/auctex") "/usr/local/var/auctex" "~/.emacs.d/auctex")
  "Directory containing automatically generated information.

For storing automatic extracted information about the TeX macros
shared by all users of a site."
  :group 'TeX-file
  :type 'directory)

Doesn't seem to be any mention of load-file-name.  There's stuff like

(defvar TeX-lisp-directory
  (file-name-directory load-file-name)

but that shouldn't affect this user option, surely?  Hm...  anybody know
what's going on?  (Or has this been fixed in the years since it was
reported?  I haven't tried to reproduce the problem.)

Yes, looks like this was fixed in ca06d68639f in auctex.

So I'm therefore closing this bug report.
