The crash happens whilst the outline view is assembling the dictionary for
the itemDidCollapseNotification so to me that would indicate a data source
problem. Perhaps the item you are collapsing has been autoreleased between
being supplied from the OutlineView's data source and when you click on
its disclosure triangle?
