Salut,

J'utilise IPython 0,10, Python 2.5 et EmacsW32 23,1 et ipython.el Rev.2927 sous Windows XP. Il plante toujours lorsque j'appelle python-shell dans Emacs. Quelqu'un pourrait-il aider sur ce problème? Merci beaucoup!

mise à jour: J'ai essayé le correctif https://bugs.launchpad.net/ipython/+bug/290228, mais cela n'aide pas.

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: 'C:\Home_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: Fernando Perez at fperez....@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' fperez....@gmail.com < C:\Home_ipython \IPython_crash_report.txt
