The behaviour of __init__ when called with an iterable Element as initializer is not consistent between different types of dense matrices:

sage: vec = vector(ZZ, [1])
sage: MatrixSpace(RR, 1, 1)(vec)
sage: MatrixSpace(CC, 1, 1)(vec)
sage: MatrixSpace(ZZ, 1, 1)(vec)
TypeError: unable to coerce entry to an integer
sage: MatrixSpace(QQ, 1, 1)(vec)
TypeError: entries must be coercible to a list or integer
sage: MatrixSpace(ZZ['t'], 1, 1)(vec)

Specialized versions probably should follow what generic matrices do.
