[BUG] alt-gr key not active

[aem34]

Hello,

System: ubuntu 15.04 - azerty keyboard
Universe sandbox version : alpha 16.1

I can't type my email address in any contact form,
because i can't type the "@" character
formed with the usual keyboard combination ALT-GR (right ALT) and "0" key
on an azerty keyboard.
It works on the rest of the system.

thank you
