It shouldn't ask you for the height of a NULL item.
This is either:
1. a bug in nsoutlineview
2. your code may be reloading the nsoutlineview in one of the delegate
methods, putting it into a "strange" state. If you see this happening
consistently, you may want to break on NSOutlineView reloadData and
see if it is getting called when it shouldn't be.

Fair enough, but the root item is never represented graphically in a
table, so there wouldn't be a need to ask for its row height…?
Anyway, I filed a radar… we'll see what happens.

Although the docs don't mention it for this method, quite often an
item of nil is used to represent the tree's root object. I would
suggest therefore returning the default height of a table cell.
