Hello,

By typing "python -V" i get 2.7.3 and by typing "ipython -V" i get 2.2.0.

Now when i am trying to open "ipython notebook" i get the following error:

ERROR:root:Exception in I/O handler for fd 3
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/zmq/eventloop/ioloop.py", line 330, in start
self._handlers[fd](fd, events)
KeyError: 3

Anyone know what is going on??
can i fix it by switching to the 0.12.1 version of ipython ... but i don't know how to do this...
