I just saw a similar error when trying to plot some text; in my case,
basemap wasn't involved.
The full error dump:
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/text.py
in draw(self, renderer)
486
--> 487 for line, wh, x, y in info:
488 x = x + posx
489 y = y + posy
TypeError: CXX : Error creating object of type N2Py3IntE
My x data were times in seconds calculated relative to a reference
date, and reducing the gap cleared up my problem.
This thread:
http://markmail.org/message/zqfgrshmq3366mtz?q=Error+N2Py3IntE
suggests that the error is due to an overflow in the underlying numerics.
And ... this is where I reach the end of my expertise.
