Hi,

I think this is covered by bug report #304296. The problem
is the x86_64 architecture - or my coding stuff ;)
Guess the problem is somewhere located in the calibration 
code.
As I don't have such a system, I first need to get one
for testing. The difference between scanimage and xsane
could be the calibration cache. Disabling that should 
make the stuff work.
