How was your day today? ;-)

One thing you could try is to start Emacs with `emacs -Q' and then eval
the AUCTeX and RefTeX relevant parts for your .emacs file in *scratch*
before loading your .tex file, maybe that helps.

I tried it with the files attached without a problem.  One thing I found
out is a bug in a regexp in `latex.el':

    (defvar LaTeX-auto-minimal-regexp-list
      '(("\\\\document\\(style\\|class\\)\
    \\(\\[\\(\\([^#\\%]\\|%[^\n\r]*[\n\r]\\)*\\)\\]\\)?\
    {\\([^#\\.\n\r]+?\\)}"
         (3 5 1) LaTeX-auto-style)
        ("\\\\use\\(package\\)\\(\\[\\([^\]\\]*\\)\\]\\)?\
    {\\(\\([^#}\\.%]\\|%[^\n\r]*[\n\r]\\)+?\\)}"
         (3 4 1) LaTeX-auto-style))
      "Minimal list of regular expressions matching LaTeX macro definitions.")

The regexp seems broken to me as fails to parse due to a \ in \refsectionmode:

    \usepackage[refsection=\refsectionmode]{biblatex}

My suggestion to other developers: Make the following change:

-       ("\\\\use\\(package\\)\\(\\[\\([^\]\\]*\\)\\]\\)?\
#       ("\\\\use\\(package\\)\\(\\[\\([^]]*\\)\\]\\)?\

But this doesn't make a difference for RefTeX.

Best, Arash
