Well, going back to look at my *own* code I see that this is wrong.  Not
setting anything in the "dummy" child node will not cause a problem because
it will be overwritten anyway when the "expand-row" callback is called.  You
only have to worry about NULL cells in the visible rows.  Sorry about the
misinformation.
