No menus for several programs

[Eduar Arley Cardona]

I've just installed Ubuntu 16.04 Beta 2 64 bits. On several programs, there are no menu items displayed on menu bar. There's just the window title, but no menu at all. However, other programs seems to work OK.

Programs that works OK (Menus are OK): chromium-browser, firefox, thunderbird, wireshark
Programs with no menus: nautilus, virt-manager, filezilla, libreoffice, totem, rhythmbox, transmission, evince, gedit
