in gtk 2.15.2, rev 22227 is causing massive crash when activating a menu item :

* gtk/gtkbutton.c: Activate the action in a regular clicked
        handler instead of the default handler, to make it work with
        derived classes which don't chain up their clicked handler.

Reverting this patch fixes the crash.

This is caused by  gtktogglebutton.c:505

GTK_BUTTON_CLASS (gtk_toggle_button_parent_class)->clicked (button);

since now, clicked is NULL.

Exemple of stacktrace : gedit, then do File / Open File :

(gdb) bt
