[sane-devel] avision segfault

[Jeremy]

I updated my batch scanimage script
(http://www.acjlaw.net:8080/~jeremy/Ricoh/scripts/bscan)

and encountered a segfault when running:
bscan --mode=8-bit --shades=2 -bw --page=Letter --comp=lzw -duplex test

resulting  from the code which tests for DUPLEX support
scanimage -h --device="${i}"


The other backends don't segfault:

for f in $(scanimage -L | cut -d  ' ' -f2); do 
  f="${f#\`}"; f="${f%\'}"; 
  echo $f; 
  scanimage -h -d "${f}" >/dev/null; 
done
