One thing is sure, this picture will never end up in qatar propaganda's newspapers...
On the other hand i saw long time back at CDG:2000 (and during the summer time,so no ice on taxi way..) An Air france Airbus A-340 with his left hand landing gear in the grass after "missing" a turn during taxi...(ok A340 is not A330 right..),So i guess nobody is immune from doing a mistake.
