This shows that you're running an old-ish version of xetex....

....and the format files you have don't match the program version.

I wonder if perhaps you have two copies of xetex around, of different  
versions.

Have you tried updating to the latest XeTeX release (currently  
0.99b)? If the installation procedure completes normally, it should  
recreate the format files and then you'll have matching software and  
format file versions -- unless, perhaps, you have an older executable  
in another directory, so the update doesn't touch it.
