I agree, but then it's not a bug in python-apt. It's really a bug caused by
our old version of pip, which doesn't natively understand PEP 440 'arbitrary
equality' clauses signified by the === marker. Even if you change
python-apt's version number it's still possible that some other installed
package will have a nonconforming version number.
Upgrading pip to the latest version is an arduous process because of all the
bureaucracy involved (and a bit of technical prerequisites), but in any case,
with the help of the upstream maintainer, I did backport a workaround in pip
1.5.6-7 (seen in Ubuntu as 1.5.6-7ubuntu1). You'll need wily though.

`pip list` would also trigger the bug, but it should be fixed now, at least in
unstable and wily. I have an ongoing task to update pip to the latest
upstream release.

I'm trying to use pip freeze, but it fails:

Note that I've patched /usr/lib/python2.7/dist-packages/pip/__init__.py to
show me the dist.
It seems that pip does not like the string python-
