    Hi Henrik,

    xsane-0.57 will solve this problem.
    The problem is that the snapscan backend returns an invalid pointer
    when sane_get_option_descriptor is called with negative values.
    Normally this sould be fixed in the backend but because there are
    other backends who return invalid pointers I decided to solve
    the problem in xsane.

    If you want a quick fix edit snapscan.c and change the test for
    if (option<max_options)

    to

    if ((option>=0) && (option<max_options))

    Bye
    Oliver
