Thanks for the pointer, Dave. I'm at WWDC this week but will give it a try on my 10.4 system when I get home. Steve

Looks very similar to a known problem on 10.4 with Core Data + NSTreeController. See http://www.cocoadev.com/index.pl?NSTreeControllerBugOrDeveloperError

The post from Frank at the bottom of the above page gives a solution that worked for me. However, you should only use this code on 10.4. The problem was fixed on 10.5.

I'm seeing a crash in -[_NSArrayControllerTreeNode _safeNodeAtIndexPath:] but I'm not really sure why. That would be "why" in the sense of what -[_NSArrayControllerTreeNode _safeNodeAtIndexPath:] might be doing or of something I should or shouldn't have done vs. saying that it crashed because of a nil pointer. :)

A little more background: I am using Karelia's iMediaBrowser framework in a project. I have created a custom media parser that generates information for the browser to display in an outline view. There is also a button in the UI that refreshes the data. It is in response to clicking that button that [someMutableArray setArray:...] is being called and then is crashing down in the bowels of AppKit.
Thoughts?
