I'm going to try your suggestion of building the latest code and using
that instead,
Re-built 1.0.27, it behaves exactly the same.
Any other ideas how to debug this?

hey simon
have you read the manpage sane-avision.5?
i don't have an avision scanner so i'm only guessing at the specific
options for your 'elderly ScanJet 5300C'. the output from
$ scanimage -n -A -d avision:libusb:003:005
would be helpful ...
where is your avision.conf file installed?
what happens if you un-comment these lines in your avision.conf file?
#option disable-gamma-table
#option disable-calibration
and run [hopefully you compiled with debug support enabled]
$ SANE_DEBUG_AVISION=7 scanimage -v -v -v \
-d avision:libusb:003:005 --format=png \
-x216 -y100 -res 200 --mode=gray \
2> /tmp/default_5300.log >/tmp/default_5300.png
forward all output files if you want ...
aloha
