a failing python script

Hi,
I found that the attached testcase works with clutter-gtk 1.0, but not on clutter-gtk 1.2

My system is running Gentoo with:
Glib 2.32.4
GTK+ 3.2
Clutter 1.10.8
Clutter-Gtk 1.2.0 (its working with 1.0.4)


I was able to capture a partial backtrace:

I can rebuild glib and gtk with debugging enabled, if you need to see more symbols. Just drop me a line.

clutter-gtk 1.3.2 is also broken (similar backtrace)

In GTK+ 3.2, GtkWidgetClass.state_flags_changed did not have an
implementation inside GtkWidget, which means that running clutter-gtk
with an older GTK+ version will crash.
