Thanks for the help everyone has given me, I've figured out the
issue. It was related to the compression that is being used on the
tif image. I guess that imagemagick uses jpeg compression by default.
The applications that were importing my converted images don't
understand jpeg compressed images (nor any compression apparently).
The images SEEMED ok in a number of apps I was using to check the
conversions but I had to dig a little deeper, apparently.

You should first try reading the image BEFORE trying to modify it!
convert image.jpg -strip -colorspace gray -colors 256 image.tif
