Setting up python-libxml2 (2.9.3+dfsg1-1ubuntu0.3) ...
Traceback (most recent call last):

This doesn't make much sense.
pycompile and /usr/share/python/debpython/version.py comes from python-minimal, and ConfigParser is from the standard python lib.
Do you have some manual python installation somewhere that is taking over the system python?
Could you try to run
    python -c 'from ConfigParser import SafeConfigParser'
and see whether you get any error? (it shouldn't print nor do anything, just return).
