I have troubles understanding gi.repository

I use this contruction in my code

from gi.repository import Gtk

But if I want to use some component I get import error

I searched and I got it worked for some components, like GtkSource, Vte, GLib, …

So my code is like

from gi.repository import Gtk, GtkSource, Vte, GLib

Everything worked fine, but if I want to add matplotlib to draw on my canvas I get and error

    enter code/usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40: Warning: specified class size for type `PyGtkGenericCellRenderer' is smaller than the parent type's `GtkCellRenderer' class size
  from gtk import _gtk

  from gtk import _gtk
Segmentation fault (core dumped) here

How can I get matplotlib working with gi.repository?

Thank you

    That’s a very good question. I’m afraid the answer might be “you can’t.” Matplotlib’s GTK backend is written for PyGTK, the old-style Python bindings for GTK. The gi.repository package is the new-style Python bindings. I don’t know one way or the other whether they can mix or not, but your results seem to indicate they can’t.
