segmentation fault with the viewer

[Josh Warner]

I got it to segfault once using the tk backend for pylab, but it wasn't 
robustly repeatable (randomly happened once out of a lot of focus 
losses/regains, and never on close).

It looked similar to routine segfaults I get for the tk backend, which I've 
never been able to track down. That's why I usually avoid the tk backend 
like the plage...

Is this reproducible on any other backends?
