- had a checkbox table with an item that had no label
- double-clicked the item (outside the checkbox)
- it failed with:

The line in question is:
	int columnIndex = (int)/*64*/tableView.clickedColumn ();
	id column = columns.objectAtIndex (columnIndex);
-->	if (column.id == checkColumn.id) return;

columnIndex is -1, so column gets null.
