I finally managed to reproduce the collision problems through a lot of angry clicking and tabbing on game load. Then it took me a couple of hours to realize that the image data failed to load correctly. Apparently I hadn't considered that the sound loading and image loading were using the same resource loader, so I had only made the texture loader thread safe (able to process multiple images at the same time) on its own. If you were unlucky an image and a sound would try to load at the same time, which XNA content pipe doesn't support. You would then get corrupt image data, which messed up the collision checker.
