The patch fixes "NameError: global name 'ErrorString' is not defined" in python-docutils

Description of problem:
/usr/lib/python2.7/site-packages/docutils/frontend.py in python-docutils
refer ErrorString() defined in docutils.error_reporting but not imported it.

This causes rst2* not worked in some specific situations such if wrong
values passed to options.

Here is a sample session log:

ssato@localhost% rst2odt foo.rst -o foo.odt

Version-Release number of selected component (if applicable): 0.8-2


How reproducible: always in some specific situations.

Steps to Reproduce:

  where xyz = html | odt | ...


Actual results:

just help or usage or some messages are out.


Additional info: The fix for this problem is trivial and
looks applied in upstream svn head.

I'll attach the patch also just in case.
