hi,
i tested this with v.transform (grass61, grass62RC2,grass63-cvs-snapshot) and the spearfish60-dataset.
v.transform
input=streams at PERMANENT
output=streams_tr45
xshift=-450000
yshift=0.0
zshift=0.0
xscale=1.0
yscale=1.0
zscale=1.0
zrot=0.0
the same output-messages:
V_ask error: Illegal row (23) in call to V_const...
i put it on the bug-list.

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.
