Package: python-pip
Version: 8.0.2-5
Severity: normal

Dear Maintainer,

After upgrading python-pip, pip-compile from the pypi package pip-tools
doesn't work anymore (installed in a virtualenv):

$ cd /tmp
$ virtualenv test
[...]
$ cd test
$ . bin/activate
$ pip install pip-tools
[...]
$ echo 'django' > req.in
$ pip-compile req.in
Traceback (most recent call last):
  File "/tmp/test/bin/pip-compile", line 11, in <module>
    sys.exit(cli())

prereleases=self.prereleases)

 line 210, in __init__
TypeError: expected string or buffer

I tracked the problem down to the following:

> /tmp/test/local/lib/python2.7/site-packages/pkg_resources/_vendor/packaging/specifiers.py(763)filter()
    761                 # Ensure that we some kind of Version class for this 
item.
    762                 if not isinstance(item, (LegacyVersion, Version)):
--> 763                     parsed_version = parse(item)
    764                 else:
    765                     parsed_version = item

ipdb> p item.__class__
<class 'pip._vendor.packaging.version.Version'>
ipdb> p Version
<class 'pkg_resources._vendor.packaging.version.Version'>
ipdb> 

I suspect this has something to do with the debundle process?
If I understand it correctly, when debuldeling is in effect,
pip._vendor.pkg_resources should not be used, in favour of
pkg_resources?

Replacing pip with a version from pypi fixes the problem:

$ pip install -U pip --force-reinstall
[...]
$ pip --version
pip 8.0.2 from /tmp/test/local/lib/python2.7/site-packages (python 2.7)
$ pip-compile req.in
[...]
django==1.9.2

Thanks,
Alexander
