iphone - UIImagePicker allowsEditing stuck in center

I have a UIImagePicker that works perfect for a type of UIImagePickerControllerSourceTypePhotoLibrary, but when I use UIImagePickerControllerSourceTypeCamera, the editing box cannot move from the center of the image. So if the image is say taller than it is wide, the user cannot move the editing box to the top square of the image.

Anyone know why this would be the case? It only happens when the source is from the camera, not the library.

Edit: Some CODE!!!

if (actionSheet.tag == 2) {
    if (buttonIndex == 0) { // Camera
        // Check for camera
        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == YES) {
            // Create image picker controller
            UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];

            // Set source to the camera
            imagePicker.sourceType =  UIImagePickerControllerSourceTypeCamera;
            imagePicker.allowsEditing = YES;

            // Delegate is self
            imagePicker.delegate = self;

            // Show image picker
            [self presentViewController:imagePicker 
                               animated:YES 
                             completion:^(void) {
                             }];
        }
    }
    else if (buttonIndex == 1) { // Photo Library
        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary] == YES) {
            // Create image picker controller
            UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];

            // Set source to the camera
            imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
            imagePicker.allowsEditing = YES;

            // Delegate is self
            imagePicker.delegate = self;

            // Show image picker
            [self presentViewController:imagePicker 
                               animated:YES 


                          completion:^(void) {
                                 }];
            }
}

So as you can see, I display them the exact same, but the camera edit acts differently than the photo library edit.

Looks like this behavior is just a bug in iOS 6... Basically you cannot move the editing box, it always bounces back to the middle unless you zoom in a bit. Hopefully they fix that soon.
