What's the shelf life of ceramic & tantalum capacitors?

What is the shelf life of unused surface-mount ceramic and tantalum (low-ESR or not) capacitors? If they are kept at a reasonable temperature and humidity (at room temperature in plastic parts bins), will they keep indefinitely, or should they be replaced after so many years?
