I have tried, but like I said, the problem appears only if I establish
the connection between the Gtk::TreeView::Column and the
Gtk::ModelView::Column. For example this code does not generate errors:

  Gtk::CellRendererPixbuf *imagerenderer =
      Gtk::manage(new Gtk::CellRendererPixbuf);
  Gtk::TreeViewColumn* iconcolumn =
      Gtk::manage(new Gtk::TreeViewColumn("Icon", *imagerenderer));
  this->tree_view.append_column (*iconcolumn);

But I have no relation and no Pixbufs. This code does not work and
produces the same errors I was talking about:

  Gtk::TreeViewColumn* iconcolumn =
      Gtk::manage(new Gtk::TreeViewColumn("Icon", this->column_set.icon));
  this->tree_view.append_column (*iconcolumn);

I have also tried with ``tree_view.pack_start (...)'' but it does not
work, too.

Regards,
