Use the "--traceback" option ("traceback" setting) to allow exceptions
to propagate to the calling code.  The program logic for exception
handling is in docutils.core.Publisher.publish().  Use "--report"
and/or "--halt" options ("report_level" & "halt_level" settings) for
fine control.  See <http://docutils.sf.net/docs/config.html>,
"[general]" section, for details.

I suspect this may be a red herring.  What Python version?  There's a
StringIO bug in Python 2.1 or 2.2.

I don't follow.  Please provide some supporting evidence.
