Parsing html using lxml and html5lib, getting "TypeError: insertDoctype() takes exactly 4 arguments (2 given)"

I\'m getting the error TypeError: insertDoctype() takes exactly 4 arguments (2 given) when using lxml and html5lib together. It seems that the insertDoctype method in lxml.html._html5builder.TreeBuild

I'm getting the error TypeError: insertDoctype() takes exactly 4 arguments (2 given) when using lxml and html5lib together. It seems that the insertDoctype method in lxml.html._html5builder.TreeBuilder (link) takes 4 args, while the html5lib code (link) calls it with 2 args. Am I somehow using this wrong?

These are the versions I'm using:

$ pip freeze
BeautifulSoup==3.2.0
distribute==0.6.14
html5lib==0.90
lxml==2.3
mechanize==0.2.4
wsgiref==0.1.2

My source code:

from lxml.html import html5parser

html5parser.document_fromstring('''<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://ww开发者_StackOverflow社区w.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html><head><title>t</title><body></body></html>''')

And the error:

Traceback (most recent call last):
  File "/tmp/t.py", line 4, in <module>
    <html><head><title>t</title><body></body></html>''')
