Help with tomatoes?

First post! Sorry for the lousy cameraphone photo, but my mother has spots on her tomatoes, and we're in disagreement about the cause. First, the photo: I think it looks like possibly a potassium or mineral deficiency, but she thinks it is the bacterial disease graywall. Underneath the spots, the meat is woody and the skin sticks to this part of the fruit, even when dipped in boiling water to be peeled. The seeds are normal, though, which doesn't seem consistent with graywall, which usually discolors the seeds and meat of the fruit. We limed and added some chicken manure for fertilizer, so hopefully that will correct the problem. This is the first year for her garden, and the soil was terrible (clay, sand, rocks) before we amended it with loads of compost, manure and other organic material using the "lasagne gardening" layering technique. Has anyone seen this before? I've searched under common tomato problems, but the photos are all worse than mine! It's not tobacco mosaic, and I don't think it's the stinkbug problem either. It only happens once in a while, it's not consistent throughtout the garden and this is only the second time I've seen it, which is why I question if it's a mineral deficiency. Thanks in advance for your help!
