Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

Be sure to consult the FAQ section in the manual before submitting
a bug report.  In addition check if the bug is reproducable with an
up-to-date version of AUCTeX.  So please upgrade to the version
available from http://www.gnu.org/software/auctex/ if your
installation is older than the one available from the web site.

If the bug is triggered by a specific (La)TeX file, you should try
to produce a minimal sample file showing the problem and include it
in your report.

Your report will be posted for the auctex package at the GNU bug
tracker.  Visit http://debbugs.gnu.org/cgi/pkgreport.cgi?pkg=auctex
to browse existing AUCTeX bugs.

Most paper size related predicates in TeX-view-predicate-list-builtin
like paper-a5 are ineffective now.

How to confirm:
0. Start an emacs sesseion on X window.  Make sure that xdvi is
   available on your system.
1. Open the following file with AUCTeX.

dummy text

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% TeX-PDF-mode: nil
%%% End:
2. Type C-c C-c RET.  The document is typeset and dvi file is produced.
3. Type C-c C-c RET.  AUCTeX suggests "xdvi FILENAME.dvi" for the
   default View command.  I expect that the option " -paper a5" is
   present in the suggested command according to the entry
      ("xdvi" ("%(o?)xdvi"
               (mode-io-correlate " -sourceposition \"%n %b\" -editor \"%cS\"")
               ((paper-a4 paper-portrait) " -paper a4")
               ((paper-a4 paper-landscape) " -paper a4r")
               ((paper-a5 paper-portrait) " -paper a5")
               ((paper-a5 paper-landscape) " -paper a5r")
               (paper-b5 " -paper b5")
               (paper-letter " -paper us")
               (paper-legal " -paper legal")
               (paper-executive " -paper 7.25x10.5in")
               " %d") "%(o?)xdvi")
   in TeX-view-program-list-builtin.  However that is missing.

The reason for this is that the current AUCTeX does not append the
documentclass options to the active styles of the document.  In the days
that the predicates did function, the options were present in the output
of `(TeX-style-list)'.  However, evaluating `(TeX-style-list)' in the
buffer of the example above yields just
("art10" "article" "latex2e" "FILENAME" "LATEX")
, which lacks "a5paper".  Thus the predicate
     (TeX-match-style "\\`a5paper\\|a5comb\\'"))
in TeX-view-predicate-list-builtin returns negative result.  I suppose
that the other predicates related to paper size in
TeX-view-predicate-list-builtin do not function anymore, too.

Skimming briefly over the commit log, this discrepancy seems to be
introduced by the following commit (sorry for the mercurial log format):
changeset:   6026:170a0f97c120
user:        Mosè Giordano <address@hidden>
date:        Thu Apr 04 15:17:23 2013 +0200
summary:     Better management of package options.
Before this commit, the function LaTeX-auto-cleanup has the following
        ;; Append them to the style list.
        (dolist (elt options)
          (add-to-list 'TeX-auto-file elt t))
I suppose these lines appended all the options of documentclass to the
active style list, but they were lost in the current LaTeX-auto-cleanup.
