 If you do not respond then I will assume that the problem was fixed by
 a more recent version.

+It looks like this was posted a while ago, but we didn't see it 
+because of some bugzilla problem. Out of date, probably fixed by a 
+later version.

+Bug#: 108233
+Product: gtkmm
+Version: 2.2
+OS: Linux
+OS Details: SuSE8.0
+Status: NEW   
+Resolution: 
+Severity: normal
+Priority: Normal
+Component: general

+Summary: GdK::gc:get_screen() will return corrupt reference
+
+The following program:
+
+------------------- snip ------------------------------
+
+#include <gtkmm/main.h>
+#include <gtkmm/window.h>
+#include <stdio.h>
+
+int main(int argc, char *argv[])
+{
+  Gtk::Main main_runner(argc, argv);
+  Gtk::Window foo;
+  foo.show_all();
+  
+  Glib::RefPtr<Gdk::GC> gc = Gdk::GC::create(foo.get_window());
+  Glib::RefPtr<const Gdk::Screen> pScreen = gc->get_screen();
+  //pScreen->reference();
+  
+  return(0);
+}
+
+------------------------- snip ----------------------
+
+produces the following output on my machine:
+
+(bug:26672): GLib-GObject-CRITICAL **: file gobject.c: line 1337
+(g_object_unref): assertion `G_IS_OBJECT (object)' failed
+Segmentation fault
+
+I haven't tested it on any other platform yet. I discovered this problem
+with gtkmm-2.2.0 (release date 01/07/2003), using gtk-2.2.1 (02/02/2003).
+The commented line (pScreen->reference()) fixes this problem. It seems to
+stem from the get_screen() methods in Gdk::GC. (source file:
+gdk/gdkmm/gc.cc in the gtkmm-2.2.0 source package). The following patch
+seems to fix this, but I haven't tested if it causes any trouble with other
+components:
+
+-------- snip -------
+
+Glib::RefPtr<Screen> GC::get_screen()
+{
+//  return Glib::wrap(gdk_gc_get_screen(gobj()));
+  return Glib::wrap(gdk_gc_get_screen(gobj()), true);
+}
+
+Glib::RefPtr<const Screen> GC::get_screen() const
+{
+  //return Glib::wrap(gdk_gc_get_screen(const_cast<GdkGC*>(gobj())));
+  return Glib::wrap(gdk_gc_get_screen(const_cast<GdkGC*>(gobj())), true);
+}
+
+-------- snip --------
+
+The old code is still here as comments. The true forces wrap to increase
+the reference counter. This prevents an attempted double-free on the
+Gdk::Screen object returned by these functions.
+
+Hope this makes any sense.
+
+Bye, Sven

+Summary: Examples/book source files not installed by 'make install'
+
+The examples source files (in examples/book) are referenced in many 
+different places in the gtkmm book (docs/tutorial). However, the 
+corresponding .cc and .h files are not installed when doing a 'make 
+install'. This means that in the installed documentation (usually located 
+in share/doc/gtkmm-2.0), a bunch of links are broken. Even worst than 
+that, the corresponding links in the tutorial would require the examples 
+directory to be installed to share/doc/examples, which is of course not 
+the best solution !
+
+My opinion is that the book/* subdirs belongs to the docs/tutorial 
+directory instead of examples. This would make it much easier to create 
+installation rules for the corresponding .cc and .h files.
