alacarte error when trying to save menu item

When you try to edit, and then save, a menu item by clicking the [ok] button, alacarte refuses to close the window. When you look at the terminal output, this is what it reports:

(alacarte:24174): Gtk-CRITICAL **: 18:52:01.059: gtk_accel_label_set_accel_closure: assertion 'gtk_accel_group_from_accel_closure (accel_closure) != NULL' failed

AttributeError: 'LauncherEditor' object has no attribute 'icon_file'

alacarte was working fine until I did a release upgrade from Ubuntu 18.04 to 20.04 to 22.04.
