Menu item creation refused if you have not uploaded your own icon image

Under Ubuntu version 22.04 Alacarte refuses to save a menu item if you have not uploaded your own icon image. I suggest that a solution be implemented to create a menu item with a default icon.

Under Debian version 11.4 the error does not occur.
2) Alacarte package Version 4.16.1-1
