New description:
Original summary by reporter: sqrt() as scalar multiple of QQbar vector
{{{
sage: QQbar(sqrt(2))*vector(QQbar, [1,2])
(1.414213562373095?, 2.828427124746190?)
sage: vector(QQbar, [sqrt(2), 2*sqrt(2)])
(1.414213562373095?, 2.828427124746190?)
sage: sqrt(2)*vector(QQbar, [1,2])
<BOOM>
}}}
It seems sqrt() generally gets treated right as an element of QQbar, but
as a scalar multiple of a vector over QQbar, it does not.

Comment:
No, I don't think so. This is just an unknown use case for the detection
of which the `NotImplementedError`s were placed. I have set the summary
accordingly. After all, the minor flag is set.
