Unfortunately I'm seeing this same behaviour again. I'm on a Ubuntu
12.04 box with the ipython 0.12.1 package installed using python 2.7.3.

When I install the latest ipython into a virtualenv:

virtualenv --system-site-packages virtualenv
. virtualenv/bin/activate
pip install --upgrade ipython

and then run ipython I drop into what looks like a python prompt which I
can Ctrl-D out of into the ipython prompt. I have no idea what is
happening. Does anyone have any clues how I might discover what's going
on here and how I can fix it?

The old version of ipython outside of the virtualenv works just fine. I
need some of the functionality in 1.1 though.
