Comment:
After the patch (with 4.3.rc0):
{{{
sage: K.<a> = QuadraticField(-3)
sage: L.<b> = K.extension(x - 5)
sage: a*b
5*a
}}}
The result was `0` before.
But
{{{
sage: b
---------------------------------------------------------------------------
IndexError
...
IndexError: tuple index out of range
}}}
The result was `5` before.
