Ah... I've seen something similar recently. The problem I had was that  
I was using plain ActiveRecord objects as items in an OutlineView  
delegate. As these don't descend from OSX::NSObject, they weren't  
being retained properly and I got a very similar crash to yours. The  
solution was to wrap the object in an OSX::ActiveRecordProxy and use  
that as the item. I don't know what you're using for your items but I  
suspect you're running into a similar problem.

Cheers,

Chris
