Thanks Marshall. I am aware of the fact that as a format QuickTime allows for each video frame to have a different duration. To my understanding, FCP only deals with QT files that have no more than one video track, right? So, in the context of FCP, and XML files exported from FCP, when would it ever make sense for a QT file to have different rates for the clip and its video file?

The genesis was unclear (as in: there was no way to figure out how he had gotten there). The footage had been shot in a Canon still camera (Mark 2 5D?).
