After some hours of searching I found the problem. Glib::RefPtr<Gtk::ListStore> m_refListModel; ... Now I tried to clear my ListStore: m_refListModel.clear (); This compiled nice, but m_refListModel was NULL after calling this. m_refListModel->clear (); This worked as I expected. After reading the documentation of RefPtr, I know the problem. This was a *really* hard to find bug! regards Andreas _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
