Somehow your interface.py file was not updated to the latest version.
You probably should uninstall SABnzbd, make sure that the /usr/share/sabnzbdplus/ directory is gone, and re-install.

You can backup your sabnzbd.ini before doing this to restore your settings!

The error indicates an incompatibility between the (probably recently updated) interface files on disk and the (older) version of the program still active. A simple restart of the program should fix this, and is automatically performed in upgrade for the init.d service included in the package.
