when exporting to odt or html, latex equations are not exported when in soure block: BUG?

[Uwe Brauer <oub@mat.ucm.es>]

Hi 

I run a relative recent GNU Emacs and org master, however please
consider the following example:

When exporting to html or odt (using dvipng in both cases) the first set
of equations in the source block are ignored.

Can somebody please confirm this, and tell me whether I should open a
BUG report.

Thanks

* A source block provides to export latex equations
#+begin_src latex :results latex replace :exports results :eval t

\begin{equation}
\label{eq:doc1:1}
\begin{matrix}
  \mathit{s}^{3}: & 1 & \mathit{K} - 6 \\
  \mathit{s}^{2}: & 5 & \mathit{K} \\
  \mathit{s}: & \frac{(4\mathit{K} - 30)}{5} & \\
  \mathit{s}^{0}: & \mathit{K}. 
  & \\
\end{matrix}
\end{equation}

So we see that 
\[
\frac{4K - 30}{5} > 0 \quad\mbox{and}\quad K > 0,
\]

\[
  K > 7.5\quad \mbox{and}\quad K > 0
\]
#+end_src

* Without the source block
\begin{equation}
\label{eq:doc1:1}
\begin{matrix}
  \mathit{s}^{3}: & 1 & \mathit{K} - 6 \\
  \mathit{s}^{2}: & 5 & \mathit{K} \\
  \mathit{s}: & \frac{(4\mathit{K} - 30)}{5} & \\
  \mathit{s}^{0}: & \mathit{K}. 
  & \\
\end{matrix}
\end{equation}

So we see that 
\[
\frac{4K - 30}{5} > 0 \quad\mbox{and}\quad K > 0,
\]

\[
  K > 7.5\quad \mbox{and}\quad K > 0
\]
