title: Delete row from uitableview crashes
body: <p>I simply try to delete a row from a <code>UITableView</code> with the following code:</p>
  
  <pre><code>- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
  {
       if (editingStyle == UITableViewCellEditingStyleDelete)
       {
           [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
       }
  }
  </code></pre>
  
  <p>The problem is that my app crashes. (GDB: Program received signal: "EXC_BAD_INSTRUCTION".)
  Anybody know why?</p>
