Comment (by novoselt):
Looking into it, what probably should raise an exception is
{{{
sage: K.lattice().submodule(K.orthogonal_sublattice())
Free module of degree 3 and rank 1 over Integer Ring
Echelon basis matrix:
[0 0 1]
}}}
while taking quotients of toric lattices by "generic" vectors and modules
is OK.
