I am trying to convert a RST file into TWIKI, using Cygwin:

CYGWIN_NT-6.1-WOW64 <HOSTNAME> 1.7.17(0.262/5/3) 2012-10-19 14:39 i686 Cygwin

This is the error I get when I try to convert RST to Twiki:
$ rst2twiki.py --traceback FILE.rst

Here is the Docutils version:
$ rst2twiki.py --version
rst2twiki.py (Docutils 0.12 [repository], Python 2.7.3, on cygwin)
