rafaelff [1] filed a deletion request for python-pyzbar [2]: upstream changed name to 'pyzbar'; this package has Python scripts in /usr/bin (no just libs); no package depends on this, while the AUR package 'authenticator' depends on 'pyzbar'. Previous maintainer created 'python-pyzbar' and 'pyzbar' as duplicates for some reason. Please remove python-pyzbar.
