An image is uploaded to Commons as CC-by-sa-2.5. A third party then makes use of the image, under the terms of the CC license. In addition to the image, they copy the description on the Image: page to use as their caption. As the text of the page is licensed under the GFDL, would this downstream user have violated the GFDL?
The content of image-pages is probably ineligible. Were it a rich description about the place? it should be on wikipedia, not in commons :P
Anyway, setting on the license notice "and dual license your image description under GFDL and the image license" could be ok. But what to do then with image page edits? The change of that user about the description... and if it's GFDL, should the history of no source, deletion requested, not copyvio appear?
