Gtk::TreeView cell background color

[Jason Burchfield <jason burchfield cas-inc com>]

When I add a Gtk::TreeModelColumn<bool>, which uses a 
Gtk::CellRendererToggle, to a Gtk::TreeView and try to change the cell 
color I get a seg fault.
Is this a bug or am I doing something wrong.  All other columns work...


tv->append_column_editable( "Test", Columns.m_col_test );


void ColorRows( Gtk::TreeView* treeview ){

   Gtk::CellRendererText* cell_renderer_text;
   Gtk::TreeViewColumn* color_column;
   vector<Gtk::TreeViewColumn*> columns = treeview->get_columns();
   Gtk::TreeModel::Children children = treeview->get_model()->children();
   Gtk::TreeModel::Row row;
   CModelColumns ModelColumns;
  
   for( int x = 0; x < children.size(); x++ ){
  
       row = *(children[x]);
      
       if( (x % 2) == 0 )           
           row[ModelColumns.m_col_color] = "grey";
          
       else
           row[ModelColumns.m_col_color] = "white";
      
       for( int y = 0; y < columns.size(); y++ ){
          
           color_column = treeview->get_column(y);
           Gtk::CellRenderer* cell_renderer = 
color_column->get_first_cell_renderer();
                  
           cell_renderer_text =
                       dynamic_cast<Gtk::CellRendererText*>(cell_renderer);
       
           
color_column->add_attribute(cell_renderer_text->property_cell_background(),
                       ModelColumns.m_col_color);   // 
<----------segmentation fault
       }
   }
}
