patch included, but unsure if it will open up more cans-o-worms.

The attachment "patch for /usr/lib/python3.3/distutils/util.py, resulted in a (thus far) successful install." seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

How can this be reproduced? Do you have a pointer to a source tree which generates this crash when trying to build it?

Does this also happen with python3.4?

This doesn't seem to involve python-distutils-extra at all, reassigning.
