Ubuntu – How to unbind Ctrl-Alt-T

shortcut-keysunity

After I've upgraded to 12.04, I cannot unbind Ctrl+Alt+T from launching gnome-terminal anymore.
I've tried disabling it completely and assigning it to another shortcut in [System Settings -> Keyboard] – nothing helps, Ctrl+Alt+T still launches terminal.
Any ideas how to get rid of it?

BTW, this breaks Ctrl+Alt+T in gnome-terminal itself, which is supposed to open new tab, but instead fires up new window.

Also, on a side-topic.
This "shortcut hell" has been a problem since introduction of unity.
Shortcuts are now configured in two different places.
Every release they add/delete/change shortcuts – so I basically have to go and figure out how to disable/remap the ones that I use in my IDE.
Now, it seems, you can't disable them completely (e.g. Alt + `) and have to override with another shortcut to unbind the default one.

What I'm really trying to ask here – does anyone know if there is a launchpad bug to fix this kind of behaviour, so I can vote \ track it? Or should I just create new one and see what happens?

On current Ubuntu metacity is no longer the default window manager, so the accepted solution no longer works. Instead there's a different setting that you can change. Set the key combination to an empty array.

In a terminal:

gsettings set org.gnome.settings-daemon.plugins.media-keys terminal '[]'

To undo the change again

gsettings reset org.gnome.settings-daemon.plugins.media-keys terminal 

In case this changes again, I found this by looking for all settings that mention "terminal"

gsettings list-recursively | grep terminal

I had this problem because it interferes with an Emacs keybinding to transpose sexps.
