Description 

A.<Y> = QQ[]
R.<X> = LaurentPolynomialRing(A)
matrix(R,2,2,[X,0,0,1])

gives a 

TypeError: Unable to coerce X (<type 'sage.rings.polynomial.laurent_polynomial.LaurentPolynomial_mpair'>) to Rational

The same problem occurs with LaurentSeriesRing, but not with PowerSeriesRing.

I have not tried to chase where the problem actually comes from.
