There is a known bug in Agg on Windows XP that appears on repeated
draws (resizing does this) that causes a segmentation fault. I've
only seen this in the context of draw markers (eg
where 'o' is a plot marker symbol. Do you have markers in your plot?
Unfortunately, even though I think I know where the bug is occurring,
I don't yet have a fix for it. If it is too annoying, you may want to
roll back to 0.71 until I figure this one out.

Oh, I get it :-)
the 'g' key is now a default part of matplotlib -- eg pressing 'g'
toggles the grid on any axes. I wrote the keypress_demo before making
this behavior default, so what you see in the demo is that you toggle
grid two times in keypress_demo, once in the default axes handling,
and once in the demo. And so it ends up turning it on and back off.
Time to update the demo!
