[bug, beamer] Frame parameters taken from example code block

[Sebastien Vauban <sva-news-D0wtAvR13HarG/iDocfnWg@public.gmane.org>]

Hello,

When having such a code block inside a frame:

--8<---------------cut here---------------start------------->8---
#+TITLE:     Org Beamer examples
#+LANGUAGE:  en
#+OPTIONS:   H:2 num:nil ^:{}
#+PROPERTY:  eval no

#+LATEX_HEADER: \lstdefinelanguage{org}{}

* ECM

** Allow frame breaks

In your Org file, writing a code such as:

  #+begin_src org :eval no
  ,** A very long "frame" with breaks
     :PROPERTIES:
     :BEAMER_opt: allowframebreaks,label=
     :END:
  #+end_src

will make that frame over multiple slides, as needed.
--8<---------------cut here---------------end--------------->8---

the frame "inherits" from the property BEAMER_opt which, though, is only
present in the example code, not in the Beamer frame itself.

See http://screencast.com/t/fc3pNAXTAhK4.

Best regards,
  Seb
