While an IDE running under Windows is hardly what I would like to work with, a bug that manifests itself only on such extreme circumstances cannot be called a showstopper.
I would worry more about other instances where this Peek() method is being misused like this, perhaps on other situations that happen more frequently than Visual Studio 2013 starts.
As a prize, a Microsoft T-Shirt, a gift card and some public recognition wouldn't hurt. The person who reported this bug did a great job of pinpointing its cause.
