KeyError in Python 3.4 under IPython 3 dev #9

nbopen fails with a KeyError under the current IPython master and Python 3.4:

$ nbopen Sao\ Paulo\ Measles.ipynb 
Traceback (most recent call last):

Running on OS X 10.10.

I've run into that too - there's a leftover server info file from IPython 2.x, when we didn't write the pid as a key in the file. I'll do something in IPython to ignore those. In the meantime, you can work around it by deleting ~/.ipython/profile_default/security/nbserver-*.json.

ipython/ipython#7123 should fix this.
