Odd "Invalid value for enum KeyCode" error

My Google analytics page is basically filled with an error saying “Invalid value for enum KeyCode”, and it’s mostly occuring in the CoreGuis. It doesn’t seem to affect anything, and a lot of the errors are referring to a line involving gamepad input.

Just curious as to what could be causing this, and since it’s associated with the CoreGuis I figured I’d ask around.

I looked at the one for the Chat module comparing it to the one in Github, and that line is just “end”. Are you sure these are from today?

Apparently it happens with Mac keyboards. See Issue #130 for more info.
