Bug in FourierTransform?

Is there anything about Slot that I don't know that explains this behaviour?

FourierTransform[Sin[t], t, #]
Out= 0

Only by changing # to p I get the correct result
FourierTransform[Sin[t], t, p]
Out= (-I)*Pi*DiracDelta[1 - 2*p*Pi] + I*Pi*DiracDelta[1 + 2*p*Pi]

It happens with Cos too, but not for imaginary exopnentials or other simpel functions like UnitBox
Bug?
