XeTeX had a feature where parentheses can be used as quote characters
when declaring fonts, so one can say:

  \font\foo=(Foo Bar)

Instead of:

  \font\foo="Foo Bar"

Since file and font names are read using the same routine, this results
in the bug you have seen. Since have been fixed in XeTeX 0.9999 (TeX
Live 2013).
