That makes sense to me -- what I don't see is why g.region rast=D_cell
should work!

It works because it reads the header-file of D_cell and sets the region to
those values. After that, of course you are not able to display any other of
your maps, because they are outside of that region. Use g.region -p to see
the effect.
