Resolution Note (fix version 1.0.0-preview.7):
What was fixed was the null reference exception itself, not being able to assign built-in images to styles in the UI Builder. Please note that this bug was not for "any image", just images that come from Unity Editor's internal built-in resources. This is still not possible (and there has always been a clear message appear when the user tries to do this), but in 1.0.0-preview.7, we fixed the null references error in the Console which was not supposed to be fired in this case.
