+Summary: Documentation tells to manually free get_path return value.
+
+The reference documentation for the method Gtk::TreeModel::get_path() tells
+you to manually free the returned Gtk::TreePath instance using
+gtk_tree_path_free(). This instruction is most probably obsolete and should
+be removed from the documentation. Developers using Gtkmm can ignore it: The
+get_path return value needn't be manually freed.

+Summary: Pango::AttrList problem
+
+I get segmentation fault from the following program.
+If I comment out the line 
+	labelAttributes.insert( attr );
+in the constructor, the program works.
+
+I have tryed with both Gtk::Fixed and Gtk::Frame. 
+If the label is displayed in the constructor the problem disappears.
+The problem seems not to be related to the use of polimorfism on the 
+widget, as I have tryed to replace Gtk::Widget *widget with Gtk::Label 
+*widget, and I get segmentation fault as well.
+
+
+
+#include <gtkmm/main.h>
+#include <gtkmm/window.h>
+#include <gtkmm/fixed.h>
+#include <gtkmm/frame.h>
+#include <gtkmm/label.h>
+
+
+
+class Screen : public Gtk::Window{
+protected:
+	Gtk::Frame screenContainer;
+	Gtk::Widget *widget;
+	//Gtk::Label *widget;
+public:
+	Screen();
+	~Screen();
+	void refresh();
+};
+
+
+Screen::Screen()
+{
+	set_default_size(600,600);
+	Pango::Attribute attr = Pango::Attribute::create_attr_size(30000);
+	Pango::AttrList labelAttributes;
+	labelAttributes.insert( attr );
+	Gtk::Label *label = manage( new Gtk::Label("4") );
+	label->set_attributes(labelAttributes);
+	widget = label;
+
+	//screenContainer.put( *widget, 300, 300 );
+  	add( screenContainer );
+  	show_all();
+}
+
+Screen::~Screen(){
+	if( widget != NULL ){ 
+		delete widget; 
+	}
+}
+
+
+void Screen::refresh()
+{
+	//screenContainer.put(*widget,200,200);
+	screenContainer.add(*widget);
+	show_all();
+	queue_draw();
+
+	return;
+}
+
+int main (int argc, char *argv[])
+{
+  Gtk::Main kit(argc, argv);
+  Screen screen;
+  screen.refresh();
+  kit.run(screen);
+  return 0;
+}
+
+
+This is what I get in gdb:
+
+Program received signal SIGSEGV, Segmentation fault.
+0x40590c0e in pango_attribute_copy (attr=0x8081248) at pango-
