Huh? I just scanned an image with the ma1509 backend, saved it with
xsane 0.90 to a .tiff file and could open it with xpaint (2.6.2)
without problems. Same with the test backend. That's with default
settings (Jpeg compression). Color mode, 8 bit/color. xpaint doesn't
seem to be able to display 16 bit images.

Maybe the bug occurs only sometimes and I had luck? However I have
never noticed any problems.
Maybe it's a problem with libtiff?
hmg@hmg1:~$ ldd /usr/local/bin/xsane
libtiff.so.3 => /usr/lib/libtiff.so.3 (0x40359000)

Preferences->setup-Image TIFF 16 bit/8bit image compression
