Seems to work fine for me with the older version that I was running,
but I upgraded to latest and I get the beamer presentation I expected.

My TeX says 

This is TeX, Version 3.1415926 (TeX Live 2009/Debian)

but I don't know whether that explains it.

Export to Latex produces

\section{And this is the second slide}
\label{sec-2}
\begin{itemize}
\item with one commented item\ldots{}
\item \ldots{} containing a \href{https://www.google.com/#q%3Dorg%2Bmode}{link} that will amaze the reader
\end{itemize}

Export to beamer produces

\begin{frame}[label=sec-2]{And this is the second slide}
\begin{itemize}
\item with one commented item\ldots{}
\item \ldots{} containing a \href{https://www.google.com/#q%3Dorg%2Bmode}{link} that will amaze the reader
\end{itemize}
\end{frame}

so the link is treated exactly the same in the two cases. Probably the
enclosing environment (\section vs \frame) is what causes the different
behavior.
