I have a button that is supposed to create a popover with a UIImagePickerController, instead it crashes. I'm not using ARC, and I have looked through many other entries and no others helped. I'm not prematurely releasing anything. Does anyone have a fix?

-(void)pickImageAction {

    if ([popoverController isPopoverVisible]) {

        [popoverController dismissPopoverAnimated:YES];
        [popoverController release];

    } else {

        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {

            picker = [[UIImagePickerController alloc] init];
            picker.delegate = self;
            picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

            popoverController = [[UIPopoverController alloc] initWithContentViewController:picker];
            popoverController.delegate = self;
                        //Crashes here
            [popoverController presentPopoverFromRect:CGRectMake(300, 300, 320, 480) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];



        }

    }


}    

-(IBAction)buttonClicked {

[self pickImageAction];

}
