Re: [matplotlib-devel] two questions

[Nadia D. <den...@st...>]

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().
