Lots of Button Events: crash and 'NSRangeException'

Hi Everyone,

I've got this strange crash bug that seems to occur when tapping on a lot of buttons on the screen. I've got about 10 buttons that all have event handlers on them. I show/hide the buttons on/off states, and also remove/add an AppProperty on each tap. The faster I tap the buttons, the sooner I get the crash and this message in the console: 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 27 beyond bounds [0 .. 25]'

var waterButtonNone = Titanium.UI.createButton({
                                backgroundImage: "../images/none.png",
