Something goes wrong when using a GTK3 backend and the mpl_toolkits. See this very minimal testcase:

>>>fromgi.repositoryimportGtk>>>importmpl_toolkits.axisartist/usr/lib/python2.7/dist-packages/gobject/constants.py:24:Warning:g_boxed_type_register_static:assertion `g_type_from_name (name)==0'failedimportgobject._gobject/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40:Warning:specifiedclasssizefor type`PyGtkGenericCellRenderer' is smaller than the parent type's `GtkCellRenderer'classsizefromgtkimport_gtk/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40:Warning:g_type_get_qdata:assertion `node!=NULL'failedfromgtkimport_gtkSegmentatiefout (geheugendumpgemaakt)

Most likely, something imports the old GTK2 bindings, run following for the same error:

>>>fromgi.repositoryimportGtk>>>importgtk

Grepping the sourcecode gives mpl_toolkits/gtktools.py where it is used, but I can't even find where it is imported.

This looks as if you do not have the development files for Gtk3 installed. Would you mind testing the attached patch? It should give you an error message to this effect.

try:
gi.require_version("Gtk", "3.0")
except ValueError:
raise ImportError("Gtk3 backend gtk3 development files to be installed.")

Missing word: "requires".
Also, this has me puzzled, because I can run the gtk3agg backend on ubuntu Precise, but I don't have the libgtk-3-dev package installed.

It seems things are packaged somewhat differently on Debian/Ubuntu than on Fedora. I think on Ubuntu, the required package is: gir1.2-gtk3.0https://launchpad.net/ubuntu/precise/+package/gir1.2-gtk-3.0

Since we don't really know what distro the user will be using, I'm inclined to change this to:

"The Gtk3 backend requires that the GObject introspection bindings for Gtk 3 are installed."

That should give a user enough to Google something by.
