Try adding the accelerators when adding actions to the actiongroup, for 
example:

       self.actiongroup.add_actions([('View', None, _('View'), '<Control>V',
None, self.on_treeview_browse_movies_row_activated),
                                      ('Edit', gtk.STOCK_EDIT, _('Edit'),
None, None,
self.on_toolbutton_edit_clicked),
                                      ('Delete', gtk.STOCK_DELETE,
_('Delete'), None, None,
self.on_toolbutton_delete_clicked)])

You also have to get the uimanager accelgroup and add it to the toplevel window before inserting the actiongroup in the uimanager. See the uimanager.py example program in the tutorial:
