	Hello,

	from the logs I see you are running SANE 1.0.22. It would be nice if you 
could test on current git version. This can be done by downloading source code 
(see http://www.sane-project.org/snapshots/ ), unpack it, then run configure 
and make (you'll need libusb-devel), don't do make install, you can test as a 
normal user without installing by running this (in the backend directory):
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL124=255
export LD_PRELOAD=.libs/libsane-genesys.so
genesys --clear-calibration --resolution 300 --mode Color  2>rl.log >rl.pnm

Regards,
	Stef
