I need to fix xetex.def's \Gread at eps as well to replace
\IfFileExists by \grffile at IfFileExists that supports spaces.

Crude workaround until grffile is fixed:

\usepackage{grffile}
\makeatletter
\@ifpackagelater{grffile}{2011/10/01}{}{%
  \let\org at Gread@eps\Gread at eps
  \def\Gread at eps#1{%
    \let\OrgGreadEpsOpenin\openin
    \def\openin\@inputcheck##1 \ifeof{%
      \OrgGreadEpsOpenin\@inputcheck"#1"\relax\ifeof
    }%
    \org at Gread@eps{#1}%
    \let\openin\OrgGreadEpsOpenin
  }%
}
\makeatother
