I don't know but it's not normal I would say. If you could reproduce
that with sperfish60 and submit a bug report with how to reproduce
instruction it could incline some Grass developer to fix it. Could you?

r.region. But it's not that straight-forward as v.transform - you have
to manually calculate the region bounds (N,S,E,W) given the shift you
need, then apply this new region bounds to your raster.
