Maybe try
[[NSNotificationCenter defaultCenter] removeObserver:nil name:nil

in your dealloc method? I think that will patch the symptom, but I
still don't understand why you're getting the original error.
I tried that, but no luck. Also, I'm doing this in windowWillClose:
in my NSWindowController subclass, not dealloc.

When my app was simply an NSDocument, it worked fine: when the

that I'm using NSDocument and NSWindowController, they aren't.
The section on Window Closing Behavior in the Document-Based
Application Overview might help:

I tried sending setShouldCloseDocument:YES to my
mainWindowController, but no change.
This bit looks important though. Makes me wonder if you've got
things wired up in IB the way they should be, or some other similar
hard-to-notice glitch.
I put together two simple test cases for my bindings/KVO problem. One
that was NSDocument-based and one NSDocument/NSWindowController-
based. In doing so, I finally figured out my problem. The NSDocument
has an object called "problem" that has the data I'm looking at. When
I set bindings in the NSWindowController, I had them still bound to
the property "problem" and added "problem" and "setProblem" methods
to my NSWindowController subclass. When I changed the bindings to
"document.problem..." and removed the NSWindowController's "problem"
and "setProblem" methods, the message "An instance 0x3434f0 of class
ExperimentalData is being deallocated while key value observers are
still registered with it." stopped appearing in the log when I closed
the window.
