[Orgmode] Problem with URLs in export to latex

[Paul Sexton]

Hi guys

My .org document contains the following sentence.

In R, procedures in the =survey= library were
used\footnote{Available at: http://faculty.washington.edu/tlumley/survey/}.

This is exported to:

In R, procedures in the \texttt{survey} library were
used\footnote{Available at: [[http://faculty.washington.edu/tlumley/survey/]
[http://faculty.washington.edu/tlumley/survey/]]}.

As you can see, the URL gets exported as an [[org link]], meaningless 
outside org.

The same thing happens with \footnote{Available at: \url{...}}

Do I have things configured wrong, or is this a bug?

thanks
Paul
