Don't use a beta test version of pygtk when a newer stable version is
available. Upgrade to pygtk 2.4.1 (2.4.0 has a bug when used with
matplotlib).

Matplotlib with pygtk <2.4.0 uses the GTK+ 2.2 GtkToolbar API
Matplotlib with pygtk 2.4.0 (or higher) uses the GTK+ 2.4 GtkToolbar API

My guess is that you are running the 2.3.x beta version of pygtk which
gives a DeprecationWarning when using a GTK+ 2.2 GtkToolbar function.
