Thanks for sharing your solution.  It sounds like you may have found a
bug in MapServer.

So I meticulously looked at what was different between a good index layer and one which set off the pink screen.  Projection?  Nope, those were good.  Spatial index?  Nope, no issue there.  It turns out that every index layer with a problem had an attribute called "group".  This item isn't needed by the viewer, and by dropping the "group" item from each index shapefile, the viewer works correctly.
