Maybe nitpicking, but these were never double initializations. You were 
creating two distinct instances.

Yes. I guess it's because GRDocument -loadDataRepresentation:ofType: calls 
-createObjectsFromDictionary: on the docView attribute, but that attribute 
might be nil. The problem would be that the NSDocument framework loads the 
document's contents before creating the UI and hence the attribute has not been 
initialized. That would explain why you were creating a fresh GRDocView in 
-init.

Set a breakpoint on NSScanner -initWithString: in gdb with condition aString = 
nil. It should tell you when this happens. I got this message myself but it 
vanished after I fixed my printer setup. So I'd expect this happens in some 
code that is called from -updatePrintInfo:.
