#fixObsoleteReferences question

I've just evaluated: SmalltalkImage current fixObsoleteReferences

and then this message came up:

"Error: Still have obsolete behaviors. See inspector"

The inspector (actually an Object Finder) shows 441 obsolete references...
Ok, I've picked a random one of those (AnObsoleteAbstractHierarchicalList) and, after doing a little exploring, found something which could be useful...

PointerFinder on: #AnObsoleteAbstractHierarchicalList

After a while a pink window appeared. Nothing inside...and no idea how to get rid of all those obsolete references.
Somebody knows what I'm supposed to do with them? Should I #do: and become all nil ? Should I inspect one by one and assign it to nil?

thanks

Just as a general point I think it needs to be reiterated that there  
are just about no circumstances where doing anything like that is  
going to actually solve a problem. For a start doing a 'foo become:  
nil' is, to say the least, idiotic. Just think about it for a moment,  
please.

I hoped it might be but you would be astonished how often it is  
suggested - or worse, tried - by people that insist on treating  
Smalltalk as one of those dead languages that need manual memory  
allocation and freeing.

Find the object(s) holding onto the obsolete objects. Somewhere,  
something considers the object(s) important. Ending up with a lot of  
obsolete references is usually a signal that some class got removed  
improperly or at least at a bad point in the sequence of whatever you  
were trying to do.

To steal ideas from one person is plagiarism; to steal from many is  
research.
