I don't think this patch is correct. I just pulled "Org-mode version
7.01trans (release_7.01h.882.g750f.dirty)" to get Carsten's revert of
the previous patch and tested against the following org file:

--8<---------------cut here---------------start------------->8---

* Foo
Here is a link to section Bar: [[Bar]]

* Bar

And here is an external link: [[http://www.google.com][google]]
--8<---------------cut here---------------end--------------->8---

When I export to LaTeX, I get this:

--8<---------------cut here---------------start------------->8---
...
\section{Foo}
\label{sec-1}

Here is a link to section Bar: \hyperref[sec-2]{Bar}
\section{Bar}
\label{sec-2}


And here is an external link: \href{http://www.google.com}{google}
...
--8<---------------cut here---------------end--------------->8---

which I believe is correct - Tom?

After I apply the patch, I get this LaTeX output:

--8<---------------cut here---------------start------------->8---
...
\section{Foo}
\label{sec-1}

Here is a link to section Bar: \href{sec-2}{Bar}
\section{Bar}
\label{sec-2}


And here is an external link: \href{http://www.google.com}{google}
...
--8<---------------cut here---------------end--------------->8---

which is wrong. Did you test the patch and if so, how?

Nick
