Colour scanning - blocks of colours rather than correct image

[Phillip Deackes <gsmh@gmx.co.uk>]

I am having a problem with my Agfa SnapScan 310 SCSI scanner. Using The
Gimp/Sane the scanner works fine when I set xscanimage to do a grescale
scan. When I set it to colour, however, I get just a series of colour
blocks. The downward spiral started a while back with previous versions of
Sane - I would get a recognisable sacn but with very bas colour fringing.
An old version (around v7) worked fine.

Any ideas?
