Comment (by Michal Čihař):
Using the private API is not required to trigger my original issue. It is
just the way I hit it. The issue can be reproduced by importing
`django.contrib.admindocs.views` or `django.contrib.admindocs.utils`:
{{{
import django.contrib.admindocs.views
import docutils.utils
from docutils.core import Publisher
publisher = Publisher()
publisher.set_components("standalone", "restructuredtext", "null")
settings = publisher.get_settings()
document = docutils.utils.new_document('<rst-doc>', settings=settings)
publisher.reader.parser.parse(":tag:`foo`", document)
}}}
It crashes with
{{{
