 Package requires gnomemm2 to be installed. Compile and start TreeViewTest.
 Clicking 'Down' button repeatedly will select rows 1 through 7. On the 8th
 click, row 8 is selected, but ScrolledWindow does not adjust the view to
 make it visible. Nor does it scroll the 8th row to be centered in the
 middle of the window.

+No, please provide a simple-as-possible test case. I will not spend my
+time reducing your test case. Your time is not more valuable than
+mine. I do want to investigate this, but you need to bring me
+something to investigate.

+Summary: Gtk::Combo does not work as expected
+
+I'm not sure that this is a bug, but I think Combo's
+signal_selection_changed should not be emitted while the combo is under
+destroy. This can be reproduced with the following code. In the program
+simply hit the 'Do it' button.
+
+<-- code.cpp -->
+/*
+    To compile use the following command:
+    g++ code.cpp `pkg-config gtkmm-2.0 --cflags --libs`
+    */
+#include <gtkmm/button.h>
+#include <gtkmm/combo.h>
+#include <gtkmm/main.h>
+#include <gtkmm/window.h>
+
+using namespace Glib;
+using namespace Gtk;
+using namespace SigC;
+using namespace std;
+
+class CrashWindow : public Gtk::Window {
+	private:
+		Combo			_combo;
+		SigC::Connection	_selection_changed;
+
+		void _do_a_crash() throw ();
+		
+	public:
+		CrashWindow() throw ();
+		~CrashWindow() throw ();
+};
+
+CrashWindow::CrashWindow() throw () : Window()
+{
+	add(_combo);
+	_selection_changed = 
+		_combo.get_list()->signal_selection_changed().connect(
+			slot(*this, &CrashWindow::_do_a_crash)
+			);
+	show_all();
+	
+	list<ustring> l; l.push_back("x");
+	_combo.set_popdown_strings(l);
+}
+
+CrashWindow::~CrashWindow() throw ()
+{
+	/* The next line solves the crash, but signal_selection_changed
+	   should be emitted when the object is destroyed?
+	   */
+//	_selection_changed.disconnect();
+}
+
+void CrashWindow::_do_a_crash() throw ()
+{
+	if (_combo.get_entry()->get_text() != "") ;
+}
+
+void do_a_crash() throw ()
+{
+	static CrashWindow* _window = 0;
+	for (int i = 0; i < 2; i++) {
+		if (_window) delete _window;
+		_window = new CrashWindow;
+		_window->show();
+	}
+}
+
+int main(int argc, char *argv[])
+{
+	Main app(argc, argv);
+
+	Window window;
+	Button button("Do it");
+	window.add(button);
+		button.signal_clicked().connect(slot(do_a_crash));
+	window.show_all();
+	
+	app.run();
+}
