It looks like this is a known bug.  The solution is to avoid any "empty mesh layers" in Modo, when exporting.  Apparently I have one such, but I'm not sure how to remedy that.  I've opened a blank scene in Modo, then imported the Vicky 1 geometry without doing anything else.  What is this empty layer, why is it there, and how do I rid myself of it?  It sounds like that should fix the problem.
