Package: ipython3
Version: 0.13-1
Severity: important

One of ipython's most heavily advertized, important, and useful features
is it's integration with pylab.

However, ipython3 does not work in pylab mode at all.

$ ipython3 --pylab

    198     if gui and gui != 'auto':

ImportError: No module named matplotlib

This can be worked around by manually installing the python3 version of
matplotlib, but there does not appear to be a way to make this working
using just Debian packages.
