Xcode 5.1: any way to suppress Revert/"Keep Xcode Version" dialog

Question

As of Xcode 5.1, when I change the project out from under Xcode (in my case, most commonly, by checking out another git commit), it throws up an annoying dialog, even when not active:

Worse, I'm using Spaces (or Mission Control... whatever the hell it's called now), and the dialog gets separated from Xcode and lost, and yet it's modal and keeps Xcode from accepting input. Sometimes I find it, or it pops up in the Xcode space. Sometimes this requires force-quit on Xcode to get control back.

Short of quitting Xcode every time I change commits, is there any way to end this madness?

Answer 1

I chose revert to disk because the "disk" is the new code which I just pulled down from my repo. "keep xcode" is the code that was sitting there before I chose to change branches or pull rebase.
