I presume that sending a notification to a deallocced object causes

Invariably! ;)
Oh, yes, it will bite you. Says so right in the documentation of -
[NSDocument close].
Funny how I read that so many times last week when overriding -
canCloseDocument: but then forget immediately.
When I had a problem like this one time I ended my -dealloc like
this:
[super dealloc] ;
self = nil ;
}
I'll try it, just looking for a 'clean' implementation, so I
unregister at the right point.
Just for completeness,
I found that I was registering for the notifications of a view in my
NSDocument's -init method, not in the -windowDidLoadNib. Therefore
the object: argument of -addObserver:selector:name:object: was nil,
thus I was getting *all* notifications. Moving the registration to -
windowDidLoadNib: sorted it all as the object I wanted to watch was
instantiated.
