Hi,

Can you try to apply the attached patch to:

cd /usr/ports/graphics/sane-backends

make clean extract patch

cd /usr/ports/graphics/sane-backends/work/sane-backends-1.0.23

cat sane-backend-debug.diff | patch -p1

cd /usr/ports/graphics/sane-backends

make all deinstall install

Maybe you can figure out exactly what line is causing the crash by 
adding more printf's like shown in the attached patch.

--HPS
