How does one break on _NSKVODeallocateLog?

One of my objects is observing my NSWindowController subclass. Running in "Debug" mode, when the controller closes I see this message:

... An instance 0x494a90 of class IVWindowController is being deallocated while key value observers are still registered with it. Break on _NSKVODeallocateLog to start debugging.

So I tried a a breakpoint on "_NSKVODeallocateLog", and one on "[NSWindowController _NSKVODeallocateLog]", but neither worked.

I googled "_NSKVODeallocateLog" and got a few hits, one of which was an earlier post here for info on this breakpoint.

Sure would be nice if someone could respond to this (for the archives) and tell the world how one does in fact break on this error.

Thanks!

David

PS: I tracked down the problem so this is purely for future reference.
