Add wiki pages to Quick Launch programmatically

Question

Hi !
I got some wierd behaviour when adding Wiki pages programmatically.

teh following code works fine exept the Home page of a wiki site.

 SPNavigationNodeCollection navigationNodes = cWeb.Navigation.QuickLaunch;

                    cWeb.AllowUnsafeUpdates = true;

                    foreach (SPNavigationNode node in navigationNodes)
                    {
                        if ("Wiki Pages" == node.Title)
                        {
                            SPNavigationNode newSiteNode = new SPNavigationNode(wikiPage.Name.Substring(0, wikiPage.Name.Length - 6), wikiPage.ServerRelativeUrl); 

                            node.Children.Add(newSiteNode, node);                            
                           
                            node.Update();

                            break;
                        }
                    }

So the problem is :
Wiki Home is not displayed in the quick launch under Wiki Pages node.
1. when quering the QL i can retreive it programmatically.
2. when I am going to /_layouts/quiklnch.aspx , the Home link is there too.

but the wiki QL wuoun't display it. is that sort of a bug/feature on wiki pages site?
