Argh.  It's a bug.  And a *stupid* typo at that.  Line 422, which reads:

                if self.getItem(id) is None: continue

Should actually read:

                if self.getItem(k) is None: continue

I guess the people doing testing for me had already upgraded their BTrees,
and didn't try packing.  I personally only tested for conversion of empty
btrees.

Um, whichever has the new BTrees.  I originally wrote up all the stuff as
2.3.x, but then I realized that the new BTrees didn't come along till
fairly late in the game, which I thought was 2.3.3, but I could be confused.

Meanwhile, nobody pack their racks...  I'm going to get this thing fixed
and re-uploaded right now.
