With breakpoints in retain and autorelease, it was possible to step through the whole tab setup process. Turns out that NSTabViewController's addChildViewController calls didSelectTabViewItem before the tab is set up properly. I'm not quite sure how that threw off reference counting, but it stopped crashing after adding a branch in didSelectTabViewItem to bypass the first call. Thanks for all the suggestions!
