Aha! This looks like an instance of the same bug the ConTeXt people  
have been complaining about, where XeTeX gets into a loop trying to  
show the contents of an overfull box. Having a non-ConTeXt way to  
reproduce it should help me pin it down, so thanks for the report!

To avoid the problem for now, you'd need to find a way to suppress the  
overfull box display; e.g., don't try to include graphics that are  
wider than \textwidth! Or if you really want a graphic projecting into  
the margin, you could put it in a box and add enough negative space to  
convince the engine that it still fits on the page.

Or set a large \hfuzz value, to suppress such warnings.

Sorry about the problem; it's pretty clear it's an internal XeTeX bug.
