Now I'm confused. How did you acquire the 300dpi image that you sent
me this morning? With xscan? If so, I guess the status is this:

- xscan works with all resolutions, but it runs slower than expected

- scan's performance is fine, but it crashes at resolutions >18dpi

Is this correct?

Also, could you send me the values of variables "i", "offset", "len",
"image", and "parm" at the point where the program gets the SIGSEGV?
(You can use gdb's "print" command for this, e.g., "print i" etc...)
