This problem also affects me (but with 14.04). If it happens not only the system shortcuts like "Ctrl+Alt+T" does not work ... also my custom keybinding which i have definded stopp working until I reboot once or twice.
My Workarround so far: Install ccsm, and deactivate the "commands" and the "gnome-compatibility". After that I got no further problems with the key-bindungs. Maybe someone can confirm this or make use of it. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

Restarting u-s-d does not help, the only way to get them back is restarting unity (which roughly equals to restarting the whole session).
