matplotlib-0.54 Win98 crash

The hard drive grinds away for a couple of seconds, then I

The good news is I can replicate it on my windows 98 box (and a
windows ME box). I've had no troubles on XP. It is triggered by
importing matplotlib.backends._gtkagg. That's all I know so far, but
I should be able to figure it out from here.

Thanks for the alert.
