Error: jedi-vim fails to load with colorama 0.3.6

After deploying a new system, jedi-vim fails to load with the following error message System: Fedora22

Error detected while processing /home/fedora/.vim/bundle/jedi-vim/autoload/jedi.vim:

The problem can be reproduced using:

vim -c 'VirtualEnvActivate' -c 'py import colorama; colorama.init()'

So, you need to have colorama 0.3.6 installed - and activated your virtualenv.

I only have colorama 0.3.3 (Arch is not up-to-date in that regard), and do not activate my virtualenvs (jedi-vim (Git master) picks up $VIRTUAL_ENV by itself).

This is what :py3 import colorama; colorama.init() causes on my Vim.

Sounds similar (the same, actually) to what @tony gets in his Neovim. I ended up having jedi-vim fail whenever I was working on a project that had pylint installed, because pylint depends on colorama>=0.3.5, and so I end up with 0.3.6. A friend of mine confirmed that replacing 0.3.6 with 0.3.5 fixes the issue and is enough for both jedi and pylint to work as expected, but doing this manually for every virtualenv I create is surely non-optimal.

Thanks for looking into it 😃
