Console warning: QuitGui.Gui??

I'm beginning to delve into the GUI's with a new code drop from a TeamMate[nothing of his doing...;) Esop] and after examining the default framework and the console.log's; I'm left with this error remaining from the default scripting, Missing file: starter.fps/client/ui/QuiteGui.gui!. I've looked around when this file gets called and can't find any reference to this file other than the excuting of it from the */inits.cs files and the .log[2 separate places]??

Closest I find might be the MessageBox.cs file; which seems to create the actual control object for leaving the game, complete with the solid black menu bar.

Is this a hardcoded reference that still needs to be included in the init.cs files? or can it be commented/deleted out of the scripting schema? Or...was this intended to leave an opening for a special dialog/menu??

I'm more curious of why it's there, not so much what it does, :); well, what it's original intention was intended, ie, forgotten to remove...etc...

Thanks!
