Invalid doctypes such as <!DOCTYPE "html"> and <!DOCTYPE> cause lxml's target parser interface to segfault if the target object defines the doctype() method.
Backtrace and executable script are attached.
Valid doctypes will not cause a segfault; nor will a target object that does not define doctype().
I've reproduced the problem on Python 2.7 and Python 3.2, using both XMLParser and HTMLParser.
Version info:

Python : sys.version_info(major=2, minor=7, micro=1, releaselevel='final', serial=0)
lxml.etree : (2, 3, 0, 0)
libxml used : (2, 7, 8)
libxml compiled : (2, 7, 8)
libxslt used : (1, 1, 26)
libxslt compiled : (1, 1, 26)
