This does indeed fix the "funky result:-75" and Oops situation.
However (sorry!) there must be something you have missed in
this. The patch leads to scans with Sane at certain resolutions
being garbled. Without the patch, 2900dpi was one resolution
that used to work fine when the scan area was set to something
that did not cause a crash. However, now I systematically get
results like this one:

When I set the resolution to 1450dpi, here is what it looks
like:

The more elaborate patch I did not try, as there was posted
some concern about this might be breaking other dependancies.
Anyone around who really knows the scanner.c code to give
us a hand on this one?
Cheers & thanks,
