This was a bug, fixed in the meantime at
(merged in Sage 9.3.beta9).9.3.beta9). In Sage 9.3.rc2 for instance:
sage: A.<t> = QQ[]
sage: B.<x, y> = QQ[]
sage: H = B.quotient(B.ideal([B.1]))
sage: f = A.hom([H.0], H)
sage: f
Ring morphism:
From: Univariate Polynomial Ring in t over Rational Field
To: Quotient of Multivariate Polynomial Ring in x, y
over Rational Field by the ideal (y)
Defn: t |--> xbar
sage: f.kernel()
Principal ideal (0) of Univariate Polynomial Ring in t over Rational Field
