Sorry for the noise.. it's ipython Also it eventually returns, it just takes forever. Something to do with the exception lookups. I am using debian wheezy with a python 2.6 virtualenv: Python : (2, 6, 8, 'final', 0) lxml.etree : (3, 3, 2, 0) libxml used : (2, 8, 0) libxml compiled : (2, 8, 0) libxslt used : (1, 1, 26) libxslt compiled : (1, 1, 26) $ ipython Python 2.6.8 (unknown, Jan 26 2013, 14:35:25) Type "copyright", "credits" or "license" for more information.

The following seems to create an infinite loop:

While the same in 3.2.3 produced an error:
etree.__version__ u'3.2.1'

Could you provide your other version details? Python? libxml2?
