[Matplotlib-users] memory problem

Hi, I have a memory problem.

I'm using: matplotlib-0.85, python 2.3.5, gtk 2.8.6 and  pygtk 2.8.2.

I create a FigureCanvasGTKAgg with a subplot and I add one Line2D to this 
subplot.

Then I add this FigureCanvas in a gtk.Window

When I destroy the gtk.Window (by the gtk method destroy),
the memory seem to be not released.

Even if I clear the subplot before destroy the gtk.window only a part of 
memory is released.

Am I missing something obvious?

Can somebody help me?

Thanks
	marco
