Bruno,
First, as a side note, even though your Windows machine is a 64-bit machine,
the fact is that you are running a 32-bit Windows, which will limit the
amount of memory any one process can use.
As for your error message, I believe that is actually something slightly
different than what I originally thought. Have you tried dealing with
path.simplfy? Which version of matplotlib are you running?
