Yeah, in my experience, the best way to handle these things and keep goodwill is to own up to them and take responsibility for what happened; and explain to your customers what happened, what went wrong, how you fixed the problem and (hopefully) the entire class of problem, and what you've done to prevent the issue in the feature. A mature and honest response goes a long way.
