[dba-VB] Exception: DataTable internal index is corrupted: '5'. on ...

Hi all

Anyone encountered this nasty bug?
It seems to have lived for years(!):

I have a Winform with a DataGridView and some bound textboxes. Data source is a DataTable.
Update goes like this:

                this.Validate(true);
                this.mediaBindingSource.EndEdit();
                this.mediaTableAdapter.Update(this.MyAdapter.Media);

Sometimes after multiple but not stressed updates, the exception error is raised.

Any ideas or workarounds?
