getVanillaItemBurnTime

No, this is on "nmd.primal.core" whatever mod that is. IFuelHandlers shouldn't be given invalid itemstacks.

something like the below would work

public static int getBurnTime(ItemStack stack)
    {
        return stack.isEmpty() ? 0 : GameRegistry.getFuelValue(stack);
    }
