Public bug reported:
scanadf (and/or sane) crashes when scanning duplex documents when using a
Fujitsu M3091DCd document scanner.
The same hardware worked perfectly with older versions of sane/scanadf.
Simplex documents (omitting the 'source' option) works well.
user@alpha:/tmp$ scanadf -d fujitsu:/dev/sg1 --source "ADF Duplex" --mode
Lineart -l 0 -t 0 -x 201 -y 297 -o pat%04d.pnm
scanadf: rounded value of br-x from 201 to 200.994
scanadf: rounded value of br-y from 297 to 279.364
