The original code

            if (g != null)
                path.Add(ApplicationBrowseableList.MakeID(g.GroupID, -1, -1, -1, ""));

            if (mg != null)
                path.Add(ApplicationBrowseableList.MakeID(g.GroupID, mg.SectionID, -1, -1, ""));

            if (pc != null)
                path.Add(ApplicationBrowseableList.MakeID(g.GroupID, mg.SectionID, pc.CategoryID, -1, ""));

            if (p != null)
                path.Add(ApplicationBrowseableList.MakeID(g.GroupID, mg.SectionID, -1, p.PostID, parentCategoryIds));

should be like this:

            int gId = -1;
            if (g != null)
            {
                path.Add(ApplicationBrowseableList.MakeID(g.GroupID, -1, -1, -1, ""));
                gId = g.GroupID;
            }

            int mgId = -1;
            if (mg != null)
            {
                path.Add(ApplicationBrowseableList.MakeID(gId, mg.SectionID, -1, -1, ""));
                mgId = mg.SectionID;
            }

            if (pc != null)
                path.Add(ApplicationBrowseableList.MakeID(gId, mgId, pc.CategoryID, -1, ""));

            if (p != null)
                path.Add(ApplicationBrowseableList.MakeID(gId, mgId, -1, p.PostID, parentCategoryIds));

otherwise there might be a NullReferenceException.

Have you received a null reference exception?

If the key of the node whose path is retrieved is a valid key, a null reference should not occur -- all of the key prefix cases populate the g variable.

Yes, I've got one when I'm browsing the content selector in my local test instance.
