IE8 Array and indexOf conflict
<p>I'm currently use jquery 1.8.3. I think it added <code>indexOf</code> to <code>Array.prototype</code> so now every of my array always contains the method indexOf as the first element. 
Doing <code>for (var i in object)</code> I always get the method infexOf as my first element and it bugged my code.</p>

<p>Bug happened on IE8 only.</p>

<p>What I want is to remove this indexOf from all arrays or anyway to hack jquery / resolve this problem.</p>

<p>PS: I'm not even sure if it's jquery is the cause of this problem</p>

<p>Thanks.</p>
