conflict between Array object and cloning events

[emile.g]

If the Array object has been added new methods, the clone(true) method will cause strange behaviour on the cloned element :

• bind events to an element
• clone the element with its events : $().clone(true)
• trigger any event of the new cloned element

=> Array added methods are executed
