Description

Below is the following code from http://python-gtk-3-tutorial.readthedocs.org/en/latest/menus.html#example doesn't show tooltips on the MenuBar even though they are defined but show tooltips for other defined objects such as the ToolBar.

Another menu system designed in Glade showed the tooltips in the menu appropriately.

Here is the code that has been slightly modified from original:
