That's a bug in xunicode. It contains the line

\let\realLaTeXring\c
\def\tipacedillaaccent{\TIPAaccent{\realLaTeXcedilla}}

This should be \let\realLaTeXcedilla\c ....

Put 
\let\realLaTeXring\r
\let\realLaTeXcedilla\c

in your document after loading fontspec to get around the bug and
notify the author.
