Yes the invalid CMap entry is present in the TTF in the above link and
it throws a notdef box without crashing. Please see my post of last
night ("xetex-graphite-now-working") for a cmap-fixed version and a
pure Gr-only version without cmap problems. I'd appreciate if you
could test both those versions and tell me what happens on your
system.

Hmm -- am going back to my low-bandwidth village today so don't have
time to download the 2 gig TL 2012 preview, but I have the TL 2011
image, so I'll test that tomorrow or so.

That's an idea too. The rsync is going on and since I wanted to test
against a stable Context, I've done:

./first-setup.sh --context=current

I can mail from my low-bandwidth village all right (just can't do
heavy downloads) so I'll get back on this later. Thanks all for your
continued support and help!
