MPMediaPickerController.showsCloudItems seems to do nothing

Question

Posted this on Apple with no luck, but now that the iOS 6 NDA is up, hoping more eyes will see it here.

I am attempting to modify an app to only allow a user to select

Answer 1

It appears to be fixed in iOS 7.

The following code works; iCloud items are not showing:

 MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic];
 picker.delegate = self;
 picker.allowsPickingMultipleItems   = NO;
 picker.showsCloudItems = NO;
