I'm running into the very same problem. I'm using matplotlib from a wxPython
application, the same versions as you (Yongtao Cui), and I get the same
error (see below) after repainting a figure many times. In my case I plot
several figures (16 figures) and I get the error with very few repaintings.
This didn't happen with matplotlib 0.90.1.
Any fix besides going back to matplotlib 0.90.1?
