Exception raised when working with ipython notebook

I used to have an ipython laptop that worked correctly in Fedora, but then tried to get an ipython notepad for julia with Pkg.build ("IJulia") and Pkg.add ("IJulia"). After that and updating my version of ipython using pip, I could no longer run ipython notebook, the following exception was raised again and again:

ERROR:root:Exception in I/O handler for fd 6
Traceback (most recent call last):
  File "/usr/lib64/python2.7/site-packages/zmq/eventloop/ioloop.py", line 346, in start
    self._handlers[fd](fd, events)
KeyError: 6
^C2014-08-12 22:51:35.024 [NotebookApp] CRITICAL | received signal 2, stopping

Any help would be greatly appreciated. Thanks in advance:)
