I figured this out.. I had a datafile that held a list of Book()
instances; then I changed Book() class a little, so here I was trying to
use old instances in the file where class was changed. I don't quite
understand why it deleted other instances from global namespace. I guess
if you do something like this, outcome is unpredictable :P.
