Pip3 fails when attempting to list only outdated packages with pip3 list -o:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/", line 215, in main
    status =, args)
  File "/usr/lib/python3/dist-packages/pip/commands/", line 157, in run
    packages = self.get_outdated(packages, options)
  File "/usr/lib/python3/dist-packages/pip/commands/", line 168, in 
    dist for dist in self.iter_packages_latest_infos(packages, options)
  File "/usr/lib/python3/dist-packages/pip/commands/", line 169, in 
    if dist.latest_version > dist.parsed_version
TypeError: unorderable types: Version() > SetuptoolsVersion()

Similar options (-u/-e/..) seem unaffected and work as expected. Note that this 
is coming from my system Python 3, i.e. currently 3.5.2, on Stretch,
and only applies to pip3. Pip2 list -o doesn't fail. I'm using Debian's 
original pip3 package. Getting same result after reinstalling (pip), so I
don't think it's locally broken. Also might not even be an upstream problem, at 
least I'm not getting the error on other platforms, as far as I can say.
