sounds about right to me i had cars do that on me, very noticable at traffic lights ect, unless its a really bad clatter i would not be too bothered.

That would depend on how noisy. When you dip the clutch, the gearbox input shaft stops turning. When you release the clutch, the shaft turns again. If it's excessively noisy it could be input shaft bearing or layshaft bearings.

If the noise difference is only slight, nothing to worry about, it's just the fact that the gears are all stationary.
