Description of problem:
When I start vim (or gvim), I get the following error message on the terminal:

$ vi /usr/share/vim/vimfiles/plugin/powerline.vim
Traceback (most recent call last):
  File "<string>", line 4, in <module>
ImportError: No module named 'powerline'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
  File "<string>", line 9, in <module>
ImportError: No module named 'powerline'
An error occurred while importing powerline module.
This could be caused by invalid sys.path setting,
or by an incompatible Python version (powerline requires
Python 2.6, 2.7 or 3.2 and later to work). Please consult
the troubleshooting section in the documentation for
possible solutions.
Unable to import powerline, is it installed?
Press ENTER or type command to continue


Version-Release number of selected component (if applicable):
powerline-2.2-2.fc22.x86_64
vim-powerline-2.2-2.fc22.noarch

How reproducible:
Always

Steps to Reproduce:
1. Just run vim in terminal
2. message appears on terminal
3. press ENTER and everything looks fine. Powerline has been imported as usual.

Additional info:
I didn't have the problem with the previous release of powerline 2.1-1.

The message "Unable to import powerline, is it installed?" comes from file /usr/share/vim/vimfiles/plugin/powerline.vim (line 112) in vim-powerline package.
