Dolphin crash cuestion

Is this a Dolphin bug ?

I have attached a TestCase.

But here's the code:

" Evaluate this "
treeModel := TreeModel withRoots: (SequenceableCollection allSubclasses).
treePresenter := TreePresenter showOn: treeModel.
treePresenter view getTextBlock: [:each | (treeModel allParentsOf:
SortedCollection) size printString].


"!!!!AFTER A FEW SECONDS EVALUATE THIS !!!!!!"

treeModel remove: SortedCollection.

My image crash.
Because SortedCollection in not any more in "treeModel" and "treeModel"
in his #getTextBlock aspect has a reference to SortedCollection (a
mismatch element).
After a few second the image crash (winXP).

I know this is tricky, but i had a bug that behaves in the same way.
(i have solved it)

Regards Bruno

Bruno, it doesn't crash for me. I just get a walkback. And another when I
dismiss it, and so on.

You are not by any chance running with the option to disable walkbacks and
go straight into the debugger enabled are you?

If so I strongly recommend you do not do that. This option was put in
because some users wanted it, but frankly it is a bad idea. If you choose to
disable walkbacks, then in situations when you have recursive errors, or
those generated from UI painting, it is very likely you will get an
unrecoverable stack overflow and Dolphin will crash.

Blair,
Do you mean User Preferences>>Debugger>>showWalkbacks ?

Because it crash with both values (true and false).
But i do not know if we are talking about the same option.

The only difference is that open a Debugger automatically.
