Hi David,
This fix seems not working for me. I am using IPython 0.10, Python
2.5, and EmacsW32 23.1. When I invoke python-shell in Emacs, IPython
crashes with the following long debugging information:
ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line statement', (14, 0))
