"runaway argument" exporting: * _is_?

[Greg Minshall]

hi.  i'm running
----
Org-mode version 8.0.1 (release_8.0.1-42-g267cbe @
/Users/minshall/usr/share/emacs/site-lisp/org/)
----

my test case is
----
#+DATE: <2013-04-25 Thu>
#+OPTIONS: H:2 texht:t
#+BEAMER_COLOR_THEME:
#+BEAMER_FONT_THEME:
#+BEAMER_HEADER:

#+BEAMER_THEME: default
#+LATEX_CLASS: beamer
#+LATEX_CLASS_OPTIONS:
#+LATEX_HEADER:
#+LATEX_HEADER_EXTRA:

* _is_?
----

exporting via "C-c C-e lO" (or, "lo"), i get an error from latex.

if i change H:2 to H:1, all (seemingly) works.  here is a diff of the
.tex file generated by each H:
----
bash greg-minshalls-mbp: {1039} diff sectbug.texH:1 sectbug.texH:2
38,39c38,39
< \begin{frame}[label=sec-1]{\underline{is}?}
< \end{frame}
---
> \section[\underline{is}?]{\underline{is}?}
> \label{sec-1}
----

am i doing something wrong?  (this is fallout converting from 7.9.3f to
8.)

cheers, Greg Minshall

Isn't it a LaTeX limitation? What would the correct LaTeX code be in
that case?

I have exactly similar problems with fboxes used for framing the tags (see
function `org-latex-format-headline-default-function'): I use the following
code for having nicer boxes around the tags:

  (format "\\hfill{}\\fbox{\\textsc{%s}}"

When such a code (\fbox) is put between the [], everything breaks... LaTeX
error...

AFAICS, there are 2 ways to solve this:

- not using the [] notation when the "short title" is exactly the same as the
  "long title"

- having an heuristic to clean the "long title" for converting it into a
  "short" one (like remove all LaTeX macros, keep text only -- not sure it's
  good, because the tags would be "glued" next to the title)

I guess the first point would make more sense. What do you think?

Best regards,
  Seb

Nicolas,

this seems to be something in beamer rather than inside "vanilla" latex.

for example, the following foo.tex file fails:
----
\documentclass{beamer}
\begin{document}

\section{\underline{is}?}
\end{document}
----

but, changing to \documentclass{article} makes things work.

i'm not a beamer expert, so i can't say what is going on.

cheers, Greg
