GTK warning after updating GTK to 2.12.9

Hi all,

A user reported the following problem,

After updating to gtk 2.12.9 this warning appears when running a wxPython application:

(python:6630): Gtk-WARNING **: gtkwidget.c:8547: widget class GtkPizza' has no property named row-ending-details’

The side effect is notebook tabs not updating correctly.

System: linux slackware 12.1

wxPython: 2.8.7.1

GTK: 2.12.9

Thanks,

Roee.
