At runtime, it is not required (only python-cffi-backend is required). This is mostly driven by the python-cffi package itself: see /usr/share/python/dist/python-cffi for details. I don't immediately know why or if this would be different in Ubuntu, and I don't immediately see what the stack trace in the Ubuntu bug report has to do with cffi being installed or not.
