I've got some NSToolbar code, which seems to have suddenly stopped working on Leopard only.

- (void) setupToolbar
{
        NSLog(@"Setting up toolbar");
        
//    [self removeObsoleteToolbarIdentifiers];

NSToolbar *toolbar = [[MMICleanerToolbar alloc] initWithIdentifier:@"CleanerToolbar"];

    [toolbar setAllowsUserCustomization:YES];
    [toolbar setAutosavesConfiguration:YES];
    [toolbar setDelegate:self];
        
NSLog(@"Setting toolbar %@ for window %@", toolbar, mMainCleanerWindow);
    [mMainCleanerWindow setToolbar:toolbar];
    // release it as well? TODO
    NSLog(@"Set up toolbar");
}

MMICleanerToolbar is a subclass of NSToolbar, but actually doesn't implement any methods, so it's an NSToolbar for all intents and purposes.

On Tiger, I can see the delegates -toolbarDefaultItemIdentifiers: method get called, followed by the NSToolbarItem calls, after the setToolbar: method.

On Leopard (10.5.2/9C31) [latest security update not installed yet], the delegate methods aren't getting called, and I get an empty toolbar, which looks to be slightly less tall than the standard toolbar with small items.

I rolled back over a few revisions of my app, and they all seem to be affected, so it doesn't seem like I've broken anything recently. The first user report I got for this was today (in fact I got two).

As I workaround, I'm checking [[toolbar items] count], after setToolbar: and manually inserting the default item set if the toolbar is empty.
