[GRASS-dev] bug in v.surf.bspline?

I'm not sure if this is a bug or if I just don't know how to use

If I make a 3D vector point map, v.surf.bspline will interpolate using the
z-coordinate fine.

However, if I try to specify a vector column as the basis for interpolation,
it will go through fine, but the result is a flat map. That is, it seems not
to correctly recognize a column specified for interpolation. I set layer=1,
but don't see what else I should do. Any suggestions?
