 * * Grep for "NULL-GError" and see if they should be taken care of
 *
 * * Although we do g_mount_unmount_with_operation(), Nautilus used to do
 *   nautilus_file_operations_unmount_mount_full() to unmount a volume.  With
 *   that, Nautilus does the "volume has trash, empty it first?" dance.  Cosimo
 *   suggests that this logic should be part of GtkMountOperation, which can
 *   have Unix-specific code for emptying trash.
 *
 * * Nautilus needs to connect to "drag-action-requested", and call
 *   nautilus_drag_default_drop_action_for_icons().
 *
 * * Nautilus needs to connect to "drag-action-ask", and return the
 *   appropriate action after running a popup menu.  It needs to call
 *   nautilus_drag_drop_action_ask().
 *
 * * Nautilus needs to connect to "drag-perform-drop", and call
 *   nautilus_file_operations_copy_move() as appropriate.
 *     nautilus_file_operations_copy_move (uris, NULL, drop_uri,
 *                                         real_action, GTK_WIDGET (tree_view),
