Right, that's because Bpp is set to 3 and not 1, and tries to
read 200% too much data; changing q->version==QC_MONO to
q->version!=QC_COLOR fixes that, so scanimage runs and exits.

Scott Laird's qcam-0.91 works fine, so it's not that my qcam
is somehow broken or misconfigured. The same results are produced
whether --test-image is on or not, so it looks like reading from the
camera is wrong for the B&W model. Still working on it...
