    _______________________________________________________

Details:

Following code and its variants (different ways of enumerating  rows and
columns) caused NSMatrix to crash:



    while([matrix numberOfRows] > 0)

    {

        [matrix removeRow:0];

    }

In matrices with incomplete rows or columns it crashes too. By incomplete row
I mean, for example rows with following number of cells per row: (4, 4, 4,
1).



Attached is a patch that fixes it.
