I doubted that either a convert-from-ext* or a mkfs with the bad 4.1.1 
would turn out to be the cause, but those are the only things /I/ am 
aware of that can trigger wild behavior like we're seeing with this 
metadata, here.

So it's certainly a bug, and not accounted for by anything know at least 
to me, which makes it a new and interesting bug.  But not being a dev, 
that's about as far as I can take it.  As CMurphy said, file a bug with 
all the various information, and hope the devs can replicate and trace it 
down.
