Whoops, poor choice of wording on my part. Yes, the wheel was out of true, meandering in the fork and contacting the brake pad. The rim wasn't "bent" like a paper clip or a bumper; it was mildly warped in one spot--presumably where the tube pushed the tire bead out of the seat and then failed.
My local shop re-trued the wheel but I'm surprised a blowout could affect a wheel to that degree. I guess I'm just used to my indestructible Sting-Ray!
