Hi Michael,

Sorry for the delay in getting back to you.  

I don't believe this error message is coming from matplotlib itself.
Rather, I think it's coming from your GUI.  If you GUI is trying to
load a font, that almost certainly means you are not using one of the
*Agg backends: TkAgg, GTKAgg or WXAgg.  Which backend are you trying
to use?  From your message I assume GTK.  If GTKAgg is an option for
you, this will likely cure your problem.

However, we would like to sort this out for plain vanilla GTK as well.
Here are a thread that might have some relevant information for you -
