ATK doesn't list all children for GtkNotebook when tab contains more than label
Submitted by Marcin
When gtknotebook have got a tab page that contains something more than label we can't access those elements in accerciser.
For example create a GtkNotebook and put a Bo that contains label and an image into the tab page, then observe the hierarchy in the accercisser. Those elements won't be show and what's worse if the image is used to close the tab, there will be no way to do this.
