Yes, this is due to a bug in XeTeX; it was identified (and fixed in  
the XeTeX source repository) during the EuroBachoTeX conference  
(thanks to Jano Kula for bringing it to my attention), but of course  
the TeXLive release was well before this date.

If you're prepared to rebuild XeTeX from the development sources, the  
problem should go away, otherwise you'll need to wait for a new  
release; sorry!
