 I'll be able to figure it out after dealing with vfs stuff :).

 I finally built the latest cvs orbit and libbonobouimm and this bug
 still exists.

+There are two problems with the example. First, the UIComponent_impl
+HelloWindow::m_servantComponent is destructed before the
+Gnome::Bonobo::Window base class. The destruction of the base class
+attempts to call methods on the m_servantComponent resulting in the
+segmentation fault you are getting. Next, the m_servantComponent is
+activiated in the Root POA but never deactivated. When program exits
+ORBit tries to clean up all still active objects. Again resulting in a
+seg fault. Thus the simplest and most hackish way to fix the problem
+is to new allocate the HelloWindow object and never delete it. I
+haven't got my head around the correct way to fix these two problems.

+Hi,
+
+I have just added a patch that reorders the destruction of members and
+bases and deactivates the servant object before destroying it. The
+result is very ugly. To do this nicely I suggest we add a class
+template to bonobomm: 
+
+// Encapsulate ownership of a single servant and automatically
+// deactivate in bonobo POA at end of lifetime.
+template <class S>
+class ServantOwner {
+protected:
+        S m_servant;
+        ~ServantOwner()
+        {
+                _orbitcpp::CEnvironment env;
+                PortableServer_POA poa = bonobo_poa();
+                                                                     
+          
+                PortableServer_Servant servant =
+m_servant._orbitcpp_get_c_servant();
+                PortableServer_ObjectId* oid =
+PortableServer_POA_servant_to_id(poa, servant, env._orbitcpp_cobj());
+                env.propagate_poaex();
+                PortableServer_POA_deactivate_object(poa, oid,
+env._orbitcpp_cobj());
+                env.propagate_poaex();

 The bug here is due to the DISABLE_DEPRECATED macros that have already
 been remove. Strangely, gtkmm2 in cvs does seem to build even with
 that slight GtkCellRenderer::render() API change in GTK+ 2.3. So not
 #ifdef seems to be needed.

+Yes, for information I build gtkmm 2.3.0 without any error
