When exporting to LaTeX, any footnotes inside a table are missing the
closing curly brace.

For example, a footnote such as:

       | Field 1[fn:: A footnote.] | Field 2 |

is exported to LaTeX as:

    \begin{center}
    \begin{tabular}{l}
     Field 1\footnote{A footnote.  \\
    \end{tabular}
    \end{center}

Note that the closing curly brace is missing from the footnote.

The code for generating the LaTeX appears to be in org-latex.el at line
2,463, and looks correct to me.  Perhaps the closing brace is removed later?
