This change in nbconvert meant that importing from nbconvert.nbconvertapp import NbConvertApp in the global scope causes a circular import. That change seems to undo the efforts of https://github.com/jupyter/nbconvert/pull/423, so there might be case to be made to clean it up on the nbconvert side, but this change should at least make this module workable with nbconvert 6 for now.
