Honestly, unless you find a Python+Powerline expert who will help, I 
suggest that you delete Powerline and look for something else. The most 
recent release is an alpha release over 2 years old. Except for the Feb 
2010 wiki updates, the project appears to be dead. Even if someone 
helped you past this, there is no evidence that the fix would applied 
back to the codebase. And what about the next bug or problem?

Otherwise, sign in and submit a new issue on the project tracker, with 
just your command line, empty config response, and traceback  (if 
allowed, I do not know) and see if you get a response.
