The purpose of this message is update the archive for those us who use
to solve problems.

Isolation:
The isolation performed was reducing this problem to the insertation
of the NSTableView to an NSView. Furthermore, it appears that this
action somehow corrupts the nib file itself, as deleting the
NSTableView, NSArrayController and the NSView, and then trying to
restore the original state, i.e. with any NSView, fails as the error
message still appears.
The last sentence should have read as follows:
Furthermore, it appears that this action somehow corrupts the nib file
itself, as deleting the NSTableView, NSArrayController and the NSView,
and then trying to restore the original state, i.e. __WITHOUT__ any
NSView, fails as the error message still appears.
Workaround:
One work around would be to implement the "numberOfRowsInTableView:
and tableView:objectValueForTableColumn:row:" methods as being
demanded in the messages, either in NSArrayController itself via a
category or in a subclass.
Probably for the same reasons why the methods in question were not
implemented in the first place, the workarounds originally purposed
does appears to result in crashes or other problems, although they have
not been exhaustively pursued.
Otherwise, while this is not a functional bug, discussions off list
indicate that this is a bone fide error message problem and not yet
another case of NSArrayController confusion.
