butane (pure) has no smell, but some have a smell (usually a Mercaptan base) added.
the best thing to do is to try fill it and then let it stand upright for a few minutes, you`re supposed to do this anyway to prevent flaring of the flame.
then have a listen for any obvious leakage, you could try putting it in a plastic bag and sealing it airtight and waiting for a while, if it`s leaking the bag will get bigger.
you could also test with a match around the base too, but only if tests 1 and 2 pass.
