Description Stefan Schramm 2010-11-12 11:45:39 UTC 
Executing the following Python script causes a segmentation fault:

import libxml2
doc = libxml2.parseDoc("<example />")
context = doc.xpathNewContext()
nodelist = context.xpathEval(None)

I guess it should rather throw some exception.

I'm not sure if the problem is in libxml2's xpath-component itself or the Python-binding.

Tested in Debian Squeeze using these packages:
python2.6 (2.6.6-6)
python-libxml2 (2.7.7.dfsg-4)
libxml2 (2.7.7.dfsg-4)
linux-image-2.6.32-5-amd64 (2.6.32-27)
Comment 1 GNOME Infrastructure Team 2021-07-05 13:22:52 UTC 
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).

If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
  https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines
and create a new ticket at
  https://gitlab.gnome.org/GNOME/libxml2/-/issues/

Thank you for your understanding and your help.
