[IPython-User] ipython Notebook kernel error on Cygwin

I realize most non-Windows devs are like "'Cygwin'? - *yawn*" :D
I'm only posting because I think this is very close to working. iPython .12
itself is fine, and I can do 'ipython notebook' and hit it at localhost with no
issues. It's only when I try to create or access a notebook that things go south:

"""

le_default'
[NotebookApp] The IPython Notebook is running at: http://127.0.0.1:8888

"""

And indeed I see a 'python2.6.exe.stackdump' in '~/'

I've seen suggestions regarding other cygwin 'Operation not permitted' errors
which were solved by running as admin; that doesn't help in this case.


The result of creating '~/Untitled0.ipynb':

}
