Segmentation fault on show() with currrent SVN on FC4 x86_64

Hi,

I'm getting a segfault on show():

This is current SVN of numpy and matplotlib, deleted build directories and all:

I attach a stack trace in case it's helpful. Any pointers on where I
should go for debugging further?

Thanks a lot,
