I downloaded the photo immediately to see the EXIF in search for the clues about which lens Klaus may be intending to review next. Other than the fact that this was taken with a 5DSR camera and a 100mm lens that doesn't leave a model description in the metadata, I haven't learned much. 
So... a Zeiss Milvus 100mm Makro-Planar? 
Sorry Klaus, that's rude of me. But I've seen similar things happen to a couple of my photos when I was using a computer with (as it turned out later) a faulty RAM module to copy the photos from the card. So while I don't argue that it was a card gone bad in your case - of course you know better what happened to you - in other cases there may be more than one thing causing this effect.
