**********************************************************************

Oops, IPython crashed. We do our best to make it stable, but...

A crash report was automatically generated with the following information:
  - A verbatim copy of the crash traceback.
  - A copy of your input history during this session.
  - Data on your current IPython configuration.

It was left in the file named:
    '/home/gsever/.ipython/IPython_crash_report.txt'
If you can email this file to the developers, the information in it will
help
them in understanding and correcting the problem.

You can mail it to: Ville Vainio at vivainio at gmail.com
with the subject 'IPython Crash Report'.

If you want to do it now, the following command will work (under Unix):
mail -s 'IPython Crash Report' vivainio at gmail.com <
/home/gsever/.ipython/IPython_crash_report.txt

To ensure accurate tracking of this issue, please file a report about it at:
https://bugs.launchpad.net/ipython/+filebug

Press enter to exit:


This error message tells me that somewhere in the background Ipython is
still active, can't completely kill its instance after exiting the session.
