[O] Bug: dates in heading break beamer export

[Daniele Pizzolli]

Hello @all,

Dates in org-format in heading break the beamer export:

Minimal case:

#+OPTIONS: H:3
* title [2013-09-29 Sun]
** section
*** frame
text

Result for beamer export:

org-latex-compile: PDF file ./beamer-bug-date.pdf wasn't produced: [undefined 
control sequence] Runaway argument

The same error for:

#+OPTIONS: H:3
* title <2013-09-29 Sun>
** section
*** frame
text

This works:

#+OPTIONS: H:3
* title (2013-09-29 Sun)
** section
*** frame
text

The export in latex for the same snippets works in all cases in version:
Org-mode version 8.2 (release_8.2-6-gd08917 ...)

Regards,
Daniele
