[IPython-dev] A long shot: weird Chinese/Win XP/Anaconda/Notebook bug

[Fernando Perez]

Hey folks,

I know this is a super long shot, but I figured I'd post it in case anyone
has an idea... At the workshop on teaching CS with the IPython notebook
that just finished up, one attendee came up with a weird bug.  The platform
was a Windows XP laptop with Chinese locale, running anaconda 1.9.1 32 bit
 (IPython 1.2.1).

Given the error was in the awful cmd.exe console and all menus were in
Chinese, I didn't do a very good job of capturing the traceback. Below is
what I was able to get. If anyone recognizes the error and there's any
chance it's something we can fix on master, that would be great.

Cheers,

f
