在 beamer 中使用西班牙语 babel

Question

我beamer从下载了一个模板http://cameron.bracken.bz/beamer-template/评论页-1#评论-734我想用它做一个西班牙语的演示，但是当我尝试使用重音符号时，它无法编译。

\documentclass[xcolor=x11names,compress,utf8]{beamer}

\usepackage{graphicx}
\usepackage[spanish]{babel}

%% Beamer Layout %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\useoutertheme[subsection=false,shadow]{miniframes}
\useinnertheme{default}
\usefonttheme{serif}
\usepackage{palatino}

\setbeamerfont{title like}{shape=\scshape}
\setbeamerfont{frametitle}{shape=\scshape}

\setbeamercolor*{lower separation line head}{bg=DeepSkyBlue4} 
\setbeamercolor*{normal text}{fg=black,bg=white} 
\setbeamercolor*{alerted text}{fg=red} 
\setbeamercolor*{example text}{fg=black} 
\setbeamercolor*{structure}{fg=black} 

\setbeamercolor*{palette tertiary}{fg=black,bg=black!10} 
\setbeamercolor*{palette quaternary}{fg=black,bg=black!10} 

\renewcommand{\(}{\begin{columns}}
\renewcommand{\)}{\end{columns}}
\newcommand{\<}[1]{\begin{column}{#1}}
\renewcommand{\>}{\end{column}}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{document}


\section{\scshape Introduction}
\begin{frame}
\title{Identificacion}
%\subtitle{SUBTITLE}
\author{
Cameron Bracken\\
{\it Humboldt State University}\\
}
\date{
\today
}
\titlepage
\end{frame}

\begin{frame}{Introduction}
\tableofcontents
\end{frame}

\section{\scshape Background}
 \subsection{frame 1}
\begin{frame}{frame 1}
\begin{itemize}
\item Item atención
\item Item B
\begin{itemize}
\item Subitem 1
\item Subtem 2
\end{itemize}
\item Item C
\end{itemize}
\end{frame}

\end{document}

此示例编译完美，但当我更改时\title{Identificacion}，\title{Identificación}它崩溃了。感谢大家的帮助！
