Comment(by jason):
This is puzzling that this works, though:
{{{
sage: V=(SR^2).subspace_with_basis([[1,1]])
sage: v=V([sqrt(2)/2,sqrt(2)/2])
sage: parent(v)
Vector space of degree 2 and dimension 1 over Symbolic Ring
User basis matrix:
[1 1]
sage: QQ(3)*v
(3/2*sqrt(2), 3/2*sqrt(2))
}}}
So apparently creating the vector manually (rather than getting it as an
eigenvector of a matrix) works okay.
