As you've already been told, you can't pickle/shelve mpl objects.  Our
solution to this is to have a native python shadow object that
contains all the bits and pieces needed to create a figure, and always
build the plots from these shadow objects.  This gives us the
advantage of being able to shelve the shadow objects and rebuild the
figures later.  Of course, we're doing this in context of a large
program using the mpl api, so if you're just using pylab, you're a bit
SOL.
