Don't handle the event if we have no children.

        * gtk/gtktreeview.c
        (gtk_tree_view_real_expand_collapse_cursor_row): Don't handle the
        event if we have no children.

        * gtk/gtkfilechooserdefault.c (trap_activate_cb):
        (tree_view_keybinding_cb):Since GtkTreeView has a keybinding
         attached to '/', we need to catch keypresses before the TreeView
         gets them.
        (gtk_file_chooser_default_class_init): add '/' to be a keybinding
        to the C-l dialog.
        (location_entry_create): Clear the text to "" when loading a file.
        This has a much better feel than putting the currently selected
        in.
