OK, this is getting thornier by the minute. Fernando gave me an
account on his system running mpl 0.83.2 and ipython CVS and I logged
in over X11 and was unable to reproduce the bug. He then logged in as
me locally so we had the same environment and got the crash.
The only two differences I can see are that I have a different X11
server on my local machine and that the delays may be different since
he is local and I am remote over ssh. So it could be some kind of
nasty GUI timing threading thingie.
If anyone has any ideas that these facts inspirec, fire away.

I am using the TkAgg backend and was hesitant to post this since everyone agrees that it works,
but I rebuilt mpl from cvs this morning with VERBOSE =True, and confirmed that ipython
still crashes. Python works fine.
I am using python 2.4.1, freetype 2.9 on MacOSX with the X11 version of Tk.
Here's some of the output of plot().
