Hello, I've been running into a strange crash for a toolbar customizer that happens only on Leopard and works fine on Snow Leopard.
My toolbar contains an item hosting a NSPopUpButton which has a menu. That menu contains regular items and a sub-menu which has its delegate assigned to the File's Owner because it's dynamic and needs to be rebuilt each time it is displayed. I have found out that the mere fact the delegate is set causes a crash when the toolbar customizer is created (through "Customize Toolbar…"). Ultimately the whole thing goes down badly inside AppKit (I'm pasting the stack below if someone wants to take a look at it). In the process of digging into this issue I also found that setting the delegate causes the entire nib to be loaded again - probably to resolve the delegate, kind of recursive. Well, I just thought this would be interesting for the list, since it's working completely fine on Snow Leopard but not on Leopard (Deployment Target of this project is 10.5). Unless of course this was foreseeable in which case I'd like to hear about it.
