Which is apparently a lie....

....which occurs because xetex thinks it finished the job successfully; 
it doesn't realize that xdv2pdf gave up.

Well, it can be avoided if you can remove the ColorSync profile from 
the JPEG, perhaps by opening it and re-saving it with a graphics app 
that gives you control of such things. But yes, it's really a XeTeX 
bug, it should handle things differently.

Would you be able to send me the relevant JPEG for testing, or is it 
something internal/proprietary? I've heard of this problem a couple of 
times, but it would be helpful to have some specific examples on hand.
