The general consensus here on the forum is to disclose everything, just to show you are telling the truth... and also just in case you have something on your record that you think is spent and won't matter, but it turns out that's not the case - if you don't declare it and then it turns out you should have, they could think you were trying to hide it. If you do declare it when you didn't need to, then it won't make a difference to the application anyway, and it shows you're an honest person.
