Ubuntu, gtk 3.10.8, incapaz de visualizar uma barra de menu feita pelo Glade

Question

Meu problema é que desenhei uma UI com o Glade, mas a barra de menu não quer ser desenhada .

Aqui está o xml , apenas uma amostra: tente verificar as propriedades . É uma barra de menus muito simples, mas não consigo encontrar o problema.

Eu tentei configurar algo nas propriedades, mas todas falharam. Alguém pode me ajudar?

Não há nada errado com o seu arquivo glade.

O Ubuntu usa o Unity, que exibe a barra de menu no topo da área de trabalho!
