I meet this problem also.When I want to login Ubuntu one by proxy ,
Ubuntu one client just show me an error 'NoneType' object has attribute 'makefile'
I know it is because of the proxy.But many others cloud file sharing clients work well.
Even though I don't want to use the others,I just hope Ubuntu one can solve this bug or problem.
