[Help] NSTableDataSource and EXC_BAD_ACCESS

I am having problems implementing a version of NSTableDataSource.
I have my own NSTableDataSource which has an array (1 dimension) with the NSTableView having 1 col. The controller class has 1 member which represents the instance of the DataSource. I alloc and init it and add my NSArray for the data. Then I setDataSource with it and reloadData. It appears in the UI for a split second and then crashes out with a EXC_BAD_ACCESS.
stack:
objc_msgSend
-[MyDataSource numberOfRowsInTableView:]
...

And the strange thing is when I click on -[MyDataSource numberOfRowsInTableView:] in the Debug Frame panel the self variable is listed "out of scope" but the NSArray (which is a member of self) is shown with the proper & valid address.

I have been struggling with the debugger for several hours now, and there does not appear to be a sophisticated memory viewer.
Any help would be appreciated.
