Using RET when rebinding keys raises error

[https://me.yahoo.com/postrockrob#52e3a]

Used RET as a keystroke for a DeleteWindow? action and saved the keybinding mode. Used RET again to trigger a new key definition, and one of two things happens: 1: the window is deleted 2: the "New key binding" message appears, so hit RET again and resulted in:
