Here is one way of catching it and handling it in a safe way:

BackgroundWorker bg = new BackgroundWorker();
object o;
bg.DoWork += (c1,c2) =>
{         
        Thread.Sleep(2000);        
        throw new IndexOutOfRangeException();
};

bg.RunWorkerCompleted += (c3,c4) => 
{

 if (((RunWorkerCompletedEventArgs)e).Error != null)
    {
        MessageBox.Show(((RunWorkerCompletedEventArgs)e).Error.Message);
    }
};
