I added comment #20. Now I'm reporting similar misbehaviour on a different system.
My wife observes that with our Fujitu fi-6130 Sheetfed Scanner Ubuntu 12.04 LTS + updates, setting the pages size, and using the Automatic Document Feeder yields a page size unrelated to the page size. If you then discard that set of scans and scan again, the page size will be correct!
This workaround is practical because the scanner is quick.
But, really, how can this stupid a bug persist for three years!
