View controller app crash

I'm trying to create an app kinda like a dictionary and i have the table view with cells working but when i click on a word to go to the detail veiw controller the app crashes and gives me a "Thread 1: signal SIGABRT" error. I'm using a plist to put my data in. I think the problem is in here somewhere in this method.

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    NSString *theInfo = [info objectAtIndex:indexPath.row];
    if(!self.detailViewController){
        self.detailViewController=[[DetailViewController alloc]
                                   initWithNibName:@"DetailViewController" bundle:nil];
    }

    self.detailViewController.detailItem = theInfo;
    [self.navigationController pushViewController:self.detailViewController animated:YES];

}
