Python error: unicode reference in descriptor_pb2.py during setup.py test

[jasonmyers]

Hi, I'm getting error running the tests after installation.

Environment (in a Python 3 virtualenv):

~/ $ sw_vers
ProductName:    Mac OS X
ProductVersion: 10.8.4
~/ $ python -V
Python 3.3.2
~/ $ protoc --version
libprotoc 2.5.0

python setup.py build seems to work fine (no errors)

~/projects/google-protobuf/python $ python setup.py build
running build
running build_py
Generating google/protobuf/descriptor_pb2.py...
Generating google/protobuf/compiler/plugin_pb2.py...
...<truncated>...
copying google/__init__.py -> build/lib/google

But then python setup.py test fails on a unicode reference:

~/projects/google-protobuf/python $ python setup.py test
running test
running egg_info

I see a bunch of these default_value=unicode("", "utf-8") references in the generated descriptor_pb2.py file. Any ideas?
