Package: ipython
Version: 0.13.2~rc2-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

After attempting to start ipython after an update, I got the following traceback:

Traceback (most recent call last):
  File "/usr/bin/ipython", line 5, in <module>
    from IPython.frontend.terminal.ipapp import launch_new_instance
  File "/usr/lib/python2.7/dist-packages/IPython/__init__.py", line 43, in <module>
    from .config.loader import Config

  File "/usr/lib/python2.7/dist-packages/IPython/external/argparse/__init__.py", line 10, in <module>
    from _argparse import *
ImportError: No module named _argparse

I tried installing python-argparse, but it had no impact.
