UIImagePickerController's pushViewController misplace pushed view behind the navigation bar

Question

When I push a view controller into UIImagePickerController object, the view controller's view is misplaced behind the navigation bar. no matter what I choose as image picker source. I present image picker modally and do the following in its delegate

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
  [[UIApplication sharedApplication] setStatusBarHidden:NO];
  [picker setNavigationBarHidden:NO];

  SecondViewController *secondVC = [[SecondViewController alloc] init];
  [picker pushViewController:secondVC animated:YES];
  [secondVC release];
}

and in SecondViewController's doing nothing special.

When I pushed the same view controller into UINavigationController's object, it is placed correctly beneath the navigation bar. What should I do additionally to use image picker as navigation controller?
