I am using the following code to create a Gtk::TreeModelFilter from a liststore
which has no rows.

    m_ListStoreRef = Gtk::ListStore::create(m_Columns);
    Gtk::TreeModel::Path m_ListStoreRootPath;
    m_ListStoreRootPath.clear();
    assert(m_ListStoreRootPath.empty());
    m_TreeModelFilterRef = Gtk::TreeModelFilter::create(m_ListStoreRef,
m_ListStoreRootPath);

However the Gtk::TreeModelFilter::create spits out "glibmm-WARNING **:
Glib::ConstructParams::ConstructParams(): object class
`gtkmm__GtkTreeModelFilter' has no property named `root'" at runtime.

I have experienced traansient crashes that I believe are due to this.  I believe
a work around would be to create the TreeModelFilter from
gtk_tree_model_filter_new () and setting the path argument to NULL, but I have
not tested this.
