*** This bug has been marked as a duplicate of bug 551670 ***
Comment 3 Nils Philippsen 2010-11-29 10:39:31 UTC 
According to the backtrace, this issue is different from bug #551670.
Comment 4 Nils Philippsen 2010-11-29 10:47:45 UTC 
This is the line where the FPE happens:

        fprintf (stderr, "%s: scanning image of size %dx%d pixels at "
             "%d bits/pixel\n",
             prog_name, parm.pixels_per_line, parm.lines,
             8 * parm.bytes_per_line / parm.pixels_per_line);

And this is why:

        parm = {format = SANE_FRAME_GRAY, last_frame = 1, bytes_per_line = 0, pixels_per_line = 0, lines = 0, depth = 8}

--> division by zero. Now it would be interesting to find out why a scan of 0px*0px is attempted, if that is permissible.

David, please run the following command to find out the default settings of your device, and post the output here:

scanimage --help

Thanks.

Options specific to device `niash:libusb:001:014':
  Geometry:
    -l 0..220mm (in steps of 1) [0]
        Top-left x position of scan area.
    -t 0..297mm (in steps of 1) [0]
        Top-left y position of scan area.
    -x 0..220mm (in steps of 1) [210]
        Width of scan-area.
    -y 0..297mm (in steps of 1) [290]
        Height of scan-area.
    --resolution 75|150|300|600dpi [150]
        Sets the resolution of the scanned image.
  Image:
    --gamma-table 0..255,... (in steps of 1)
        Gamma-correction table.  In color mode this option equally affects the
        red, green, and blue channels simultaneously (i.e., it is an intensity
        gamma table).
  Scan Mode:
    --mode Color|Gray|Lineart [Color]
        Selects the scan mode (e.g., lineart, monochrome, or color).
  Enhancement:
    --threshold 0..100% (in steps of 1) [inactive]
        Select minimum-brightness to get a white point

I hope this helps,

--Dave
