Obtener la imagen de la biblioteca de fotos varias veces muestra un error

In my iPhone app , when I use UIImagePickerControllerSourceTypePhotoLibrary as the source type, after opening it for 5 times , I get :

<Error>: More than maximum 5 filtered album lists trying to register. This will fail.

in my console.And also the image picked is gone.

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]==YES) {

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;    
imagePicker.allowsEditing = YES;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release]; 
}

And in method:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

I dismiss the modalviewController.
