[XeTeX] strange problem when rendering

[Cyril]

While rendering some text, I'm getting strange test added to the  
document.
(o).fd Text (o).fd comes up when I write \={o}, but only on the first  
one of the document.
Where does that come from?
For example here:
------------
%&program=xelatex
%&encoding=UTF-8 Unicode
\documentclass[a4paper,12pt]{article}
\usepackage{fontspec}
\setromanfont{Hoefler Text}
\usepackage[french]{babel}
\usepackage{CV}

\begin{document}
\pagestyle{empty}

\begin{center}
\huge{\textsc{Curriculum Vitæ}}
\vspace{\baselineskip}

\Large{\textsc{Cyril Niklaus}}
\end{center}
\vspace{1.5\baselineskip}

\section{Adresse}
\begin{flushleft}
   Saky\={o}-ku \\
   Ky\={o}to 606-0025\\
   Japan \\
\end{flushleft}

\end{document}
gives this:

Any ideas why?
