weird behavior with TreeModel

[John Taber <jtaber johntaber net>]

Has anyone else had problems with TreeModel?
1) If I try to append rows after using TreeModel.clear(), it segfaults.
2) If I try to define a column as reorderable - it does not compile but 
if I put it in a loop thru all the columns it compiles okay.
3) I'm getting weird behavior when using a table refresh function 
(setListToDisplay) - sometimes the view does not load the data, some 
times I get a glibmm memory error.

I'm running gtkmm 2.6.1 with gtk 2.6.4 with gcc 3.3.5 on debian sid

Here's excerpt of what I've been using - anything wrong in what I'm doing?

in .h file:
    virtual void menuTreeOnClicked(const Gtk::TreeModel::Path& path,
        Gtk::TreeViewColumn* column);
    //------ menu tree ----------
    class ModelColumns : public Gtk::TreeModel::ColumnRecord {
    public:
        ModelColumns() {
            add(id);
            add(name);
        }
        Gtk::TreeModelColumn<int>id;
        Gtk::TreeModelColumn<std::string>name;
    };
    ModelColumns menuColumns;
    Gtk::ScrolledWindow menuWindow;
    Gtk::TreeView menuTreeView;
    Glib::RefPtr<Gtk::ListStore> menuTreeModel;

in .cpp file
    //---------- menu tree  -------------------------
    menuTreeModel = Gtk::ListStore::create(menuColumns);
    menuTreeView.set_model(menuTreeModel);
    //Gtk::TreeModel::Row row = *(menuTreeModel->append());
    //row[menuColumns.id] = 0;
    //row[menuColumns.name] = "";
    menuTreeView.append_column("ID", menuColumns.id);
    //(menuColumns.id).set_reorderable();
    menuTreeView.append_column("Name", menuColumns.name);
    for(int i=0;i<2;i++) {
        Gtk::TreeView::Column* mColumn = menuTreeView.get_column(i);
        mColumn->set_reorderable();
    }
    menuWindow.set_policy(Gtk::POLICY_AUTOMATIC, Gtk::POLICY_AUTOMATIC);
    menuWindow.add(menuTreeView);
    menuTreeView.signal_row_activated().connect(sigc::mem_fun(*this,
          &LanduseListDialog::menuTreeOnClicked) );
.....
void LanduseListDialog::setListToDisplay(std::vector<Data*>data) {
    if (data.empty()) {return;}
    //menuTreeModel.clear();
    Gtk::TreeModel::Row row;
    for (uint i=0;i<data.size();i++) {
        row = *(menuTreeModel->append());
        row[menuColumns.id] = data[i]->getid();
        row[menuColumns.name] = data[i]->getname();
    }
}
