* src/hildon-bread-crumb-trail.c (hildon_bread_crumb_trail_class_init): Add a new signal "move-parent", bind Escape and BackSpace to it. The handler will fake an activation on the previous to the last item of the trail, so the effect can be overrided by the developer as usual. Also change the callback for the back button to do the same thing, so its effect can be overrided too.
