Alt/Meta escape keys no longer work

The latest version of VTE in Maverick broke alt/meta escape keys. The terminal no longer recongnizes when left alt is being held down and right alt only allows for the file menus to be called up. The actual terminal just passes whatever combo key was pressed with the alt combo.

As far as I can tell, nothing is wrong with the keyboard or alt, because the alt key still works in all other programs, such as compiz and openoffice.

The reason I believe this a flaw in VTE, is because it only affects libvte based terminals, such as: gnome-terminal, terminator, and xfce4-terminal. Xterm and Aterm still work with alt/meta.
