[powerdot] enumerate breaks down with spanish

Thanks a lot for your speed in the previous questions.

With the updated package, the previous example works fine, but I founded a
new error: the enumerate environmenent. It works with 'catalan' and with
'english', but it brokes down with 'spanish'.

The LOG file has this message:

! Use of \\enumerate doesn't match its definition.
\@ifnextchar ... \reserved@d =#1\def \reserved@a {
                                                  #2}\def \reserved@b
{#3}\f...

------An example:------

\documentclass[style=sailor]{powerdot}
\usepackage[spanish]{babel}
\begin{document}
\begin{slide}{slide1}
\begin{enumerate}
\item first item
\end{enumerate}
\end{slide}
\end{document}
