It seems that the delegate is not valid, I get it when I call anything on the delegate, for instance when I replace the whole rebuildTrackingAreas implementation with something like NSLog(@"%@", [self delegate]);. However, the debugger does not say the _delegate is out of scope, though it only gives an "isa" in its outline.

I'm pretty sure the delegate has not been released, otherwise I would see much worse crashers much earlier. It's the main window controller of the document that owns the nib. If that were released, I would also get the crashes if I would never even call this methods, which is most definitely not the case.
