I think Andrey said he was leaving for a week, so I don't think he'll be 
testing now.

But Andrey - if you are on-line and have access to the machine, one thing 
to try would be to just do a 

	git revert e872154921a6b5

in case it really was that particular commit. It seems to revert cleanly 
(although I didn't actually check if the result then compiled/worked).

And a "git bisect" would obviously be wonderful in case it wasn't.
