Ubuntu 12 has introduced important changes with respect to "glib" (and
depending packages). In fact, there are now two quite incompatible
implementations - the old "static" one and a new "dynamic" one.
It looks as if in your case, old and new implementations were mixed.

I had a similar problem when upgrading to "Ubuntu 12.4". In my case,
it turned out that my (custom) "PYTHONPATH" setting was responsible for
getting into the incompatibility.


The new way to use "gtk" is via the "gi" (probable "gnome interface")
module. It looks like:

from gi.repository import Gtk,GdkPixbuf,GObject,Pango,Gdk,Gio
