I suspect that you have two instances of AUCTeX installation.  In your
previous message, I read
----------------------------------------------------------------------
current state:
==============
[...]
 TeX-style-path '("~/.emacs.d/auctex" 
"/home/boffi/.emacs.d/elpa/auctex-12.1.2/style" 
"/home/boffi/.emacs.d/auctex/auto"
                  "/home/boffi/.emacs.d/auctex/style" "auto" "style")
----------------------------------------------------------------------
which looks like that you have AUCTeX 12.1, while the "Subject" header
begins with "...12.2.0" which suggests that you have 12.2.

Look into ~/.emacs.d/elpa/ and see what directories are there.  If you
have both auctex-12.1.2 and auctex-12.2.0, delete the former.  And if
you have customized `TeX-style-path', erase (or modify) the
customization so that you can load from AUCTeX 12.2.  Then restart
emacs.
