a fix is posted but I'm not comfortable merging in 1.0.x since it will

I have the exact same issue. I create a new MetaData, use tometadata to
copy the first to the second, and then if I use the second metadata it
works fine. But if I pickle and unpickle it first then it doesn't work. So
something about pickling/unpickling is breaking it.
