Can't unset window shortcut

I somehow set konsole to activate an open instance using ctrl+shift+t which also happens to be browsers default re-open closed tab shortcut. I want to unset this window shortcut on console but I cannot figure out how to do so.

I've looked through the special window settings, special application settings and could not find anything there. I can temporarily unset the shortcut, listed as "Activate Window (Wallpapers:bash {Ctrl+Shift+T})", in the global shortcuts but when I restart my computer it will return. I even tried resetting all the global keybindings to default but that did not stick either.

Running:
Kubuntu 12.04.1
KDE 4.8.5

Wow I'm surprised this is such a difficult question to answer.
