Uma atualização recente parece ter corrigido o problema.
Não consigo executar o Ubuntu Tweak. Parece ter um problema com o Python ou algo assim, mas não tenho certeza.
Aqui está a saída:
/usr/lib/python2.7/dist-packages/gi/overrides/Gtk.py:47: RuntimeWarning: You have imported the Gtk 2.0 module. Because Gtk 2.0 was not designed for use with introspection some of the interfaces and API will fail. As such this is not supported by the pygobject development team and we encourage you to port your app to Gtk 3 or greater. PyGTK is the recomended python module to use with Gtk 2.0
warnings.warn(warn_msg, RuntimeWarning)
