Shortcut for opening a new window does not work after reopening Terminix

[dsboger-zz]

I've assigned the shortcut <Ctrl><Shift>n to open a new window. It works fine until I close and reopen Terminix. The shortcut assignment is still shown in the settings, but it does not work. If I reassign it, then it starts working again. I think it only affects "New window" action, as I assigned other shortcuts and they work fine.

As a side node, the shortcut is actually registered as <Primary><Shift>n, and in any assignment I make Ctrl is registered as Primary. I don't know what Primary means, but it is strange, as the stock shortcuts are correctly registered as Ctrl.
