iOS - removeEventListener crashes app only on device.

    Details

      Description

      Run this code on the device and the app will crash after adding and then removing the event listener on the orientation - after changing the orientation.

      var win1 = Ti.UI.createWindow({
      	orientationModes:[1,2,3,4]
      });
      var addCount = 0;
      var btnAdd = Ti.UI.createButton({ 
      	title: "addEvent",
      	width: 200,
      	height: 50,
      	top: 20
      });
      var btnRemove = Ti.UI.createButton({ 
      	title: "removeEvent",
      	width: 200,
      	height: 50,
      	top: 200
      });
      var orientationCallback = function(e){
      	Ti.API.info("*** orientationCallback called ***");
      };
       
      btnAdd.addEventListener('click', function(){
      	Ti.API.info("*** ADDING ORIENTATIONCHANGE EVENT");
      	Ti.Gesture.addEventListener('orientationchange', orientationCallback);
      	if(addCount > 0){
      		Ti.API.info("*** ROTATE NOW");
      	}
      	addCount++;
      });
       
      btnRemove.addEventListener('click', function(){
      	Ti.API.info("*** REMOVING ORIENTATIONCHANGE EVENT");
      	Ti.Gesture.removeEventListener('orientationchange', orientationCallback);
      });
       
      win1.add(btnAdd);
      win1.add(btnRemove);
      win1.open();

      And this is from Xcode's console:

      [INFO] *** ADDING ORIENTATIONCHANGE EVENT
      [INFO] *** orientationCallback called ***
      [INFO] *** orientationCallback called ***
      [INFO] *** REMOVING ORIENTATIONCHANGE EVENT
