[Orgmode] Problem in org + beamer on B_frame BEAMER_env for subsections with BEAMER_FRAME_LEVEL: 0

[Olivier Berger]

Hi.

It seems to me it's currently impossible to use a custom frames
sequencing in org + beamer, as only positive values of
BEAMER_FRAME_LEVEL seem to be working here.

I'm trying to use the following simple slides document below, but it
fails with :
        ! You can't use `\end' in internal vertical mode.
        \enddocument ... \endgroup \deadcycles \z@ \@@end 
                                                          
        l.60 \end{document}
                           
        
        ! LaTeX Error: address@hidden on input line 58 ended by \end{document}.
        
I guess it's because of the latex generated being :
        \begin{frame}
        \frametitle{Introduction}
        \label{sec-1}
        
        hehe\footnote{hehe }
        coin
        \begin{frame}
        [SNIP]
        \end{frame}
        \end{frame}
        

being generated instead of :
        \begin{frame}
        \frametitle{Introduction}
        \label{sec-1}
        
        hehe\footnote{hehe }
        coin
        \end{frame}
        \begin{frame}
        [SNIP]
        \end{frame}

Is this a known bug, or maybe linked to my latex beamer version
somehow ?
(org-mode being 7.01h-1 "unstable" Debian package)

Couldn't find a mention of this problem by googling, but may have missed
it.

Thanks in advance.

Best regards,
