segmentation fault on parsing url

[nix]

Noticed that BeautifulSoup causes segmentation fault in python interpreter for url mention below in the the steps to reproduce.
Python version : 2.7.1+
OS : Ubuntu (2.6 kernel)

Attached is the script which reproduces this behavior.
This is only for a specific site which is mentioned in the script.

On python shell execute the following steps to reproduce.
import urllib2
from bs4 import BeautifulSoup
sp = BeautifulSoup(urllib2.urlopen('http://keetsa.com/').read())

This is a bug in lxml. You can work around it by parsing the markup using html.parser or html5lib parser instead of lxml.
