IOS 5 black screen after segue

Question

I have an iOS 5 app with a storyboard and two scenes. Scene 1 is a selection list, while Scene 2 shows the details for each selection.

In Scene 1, I need to pass a variable, and I do this with:

//Handles the selection 
-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
    Guests *myGuests =[guestList objectAtIndex:[indexPath row]];

    selectedGuest = [[NSString alloc] initWithFormat:@"You have selected %@", myGuests.guestID];

    [self performSegueWithIdentifier:@"TGG" sender:self];
}

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    if([[segue identifier] isEqualToString:@"TGG"]){
        GuestDetailsViewController *vc = [segue destinationViewController];
        [vc setGuestSelected:selectedGuest];
    }
}

In Scene 2 (details), I use this to make sure the right variable is obtained as

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad
{
    NSString *msg = [[NSString alloc] initWithFormat:@"You have selected %@", guestSelected];
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Selection" message:msg delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];          

     nameCell.textLabel.text= msg;

    [super viewDidLoad];
}

All this works fine, and the right variable is displayed in the warning window and a transition to a new scene takes place. HOWEVER, a warning window displays a total of 5 times over and over, and upon completion, the entire window turns black. None of my scene (Scene 2) is displayed at this point. Therefore, I know that I have the right segment, it goes as desired, I just don’t see anything on my screen.
