Just for the record, for what I need it works, but it's easier to catch an exception than a segfault :)
import lxml.etree xmldoc = lxml.etree.fromstring('<?xml version="1.0"?><req><oml><section></section></oml><callback>update_preview_code</callback></req>') omlnode = xmldoc.find('oml') lxml.etree.tostring(omlnode) '<oml><section/></oml>'

Okay, it shouldn't segfault when it doesn't get a node but None instead. I need to check what ElementTree does and mimic this behavior. :) Regards, Martijn

Fixed now on svn; it raises an AssertionError now. Thanks for the bug report! Regards, Martijn
