NSArrayController/NSManagedObject Runtime Error: 'Selector Not Recognized'. What Selector?

Greetings:
I'm having a tough time tracking down the source of a 'selector not recognized' error:


*** -[NSArrayController presentError:]: selector not recognized [self = 0x388df20]

*** NSRunLoop ignoring exception '*** -[NSArrayController presentError:]:
selector not recognized [self = 0x388df20]' that raised during posting of delayed perform with target 38c49b0 and selector 'invokeWithTarget:'


============

This happens soon after startup of the application.

I tracked it down to a specific simple NSManagedObject. If I change the binding to a different MO, the error disappears.
The MO suspect is merely bound to an NSArrayController via attribute and the MOC's parameter binding.
Nothing else; not connected to any GUI at present.


I've tried:
1) Rebuilding the project piece-by-piece from an earlier backup;
2) Replacing the current NSArrayController with a new one;
3) Remove nearly all the elements within the MO;
4) Change the MO's NSManagedObject class to a customized class with attribute accessors;
5) Disconnected any NSNotifications associated with values within the MO.


Nothing helps.
I didn't introduce any selector;  it's essentially a plain-vanilla MO.

Question:
1) How can I determine the EXACT selector the run-time is complaining about?



Any ideas?

Ric.
