New issue 4077 by ppue...@googlemail.com: laplace_transform(diff(y(t), t, 2), t, s) not calculated
http://code.google.com/p/sympy/issues/detail?id=4077

t = symbols('t', real=True, positive=True)
w = symbols('w', real=True)
s = symbols('s')
y = Function('y')
laplace_transform(diff(y(t), t, 2), t, s).doit()

Does not calculate transform and return:
LaplaceTransform(Derivative(y(t), t, t), t, s)
