thanks for the help,

but after fiddling a bit with no success in my .dtx file,
I realized after adding this to the end
of my .emacs (or rather in a file .emacs.d/init.el, which is loaded
from .emacs) that M-x latex-mode issued an error.
Wrong type argument: characterp, "everb"

The *Messages* buffer:

My AUCTeX is I believe still in version 11.85

in preview.el, I found:

;; $Id: preview.el,v 1.285 2010/10/14 19:30:38 angeli Exp $

however in my tex-site.el I have

(defconst AUCTeX-version "11.86"
    "AUCTeX version.
If not a regular release, the date of the last change.")

(defconst AUCTeX-date "2010-02-21"
  "AUCTeX release date using the ISO 8601 format, yyyy-mm-dd.")

Sorry about the mess, I think the tex-site.el is a remnant
of an attempt to use 11.86, but that stuff in auctex/ is
from 11.85. All files have modification dates March 2011.

I recall spending on two occasions at least quite
a bit of time on wanting to install a more recent AUCTeX,
but each time I ended up having various problems

(including some
with preview; currently I don't use at all preview).
