error message from gtk::appchooserdialog



Here is the code..

Glib::RefPtr<Gio::File> file = Gio::File::create_for_path(filepath);
Gtk::AppChooserDialog *dialog = new Gtk::AppChooserDialog(file, *this);

if ( dialog->run() == Gtk::RESPONSE_OK ) {
    Glib::RefPtr<Gio::AppInfo> appinfo = dialog->get_app_info();
    appinfo->launch(file);
}
dialog->hide();

This is the message i get when the above code is executed..

glibmm-WARNING **: Glib::ConstructParams::ConstructParams(): object class "gtkmm__GtkAppChooserDialog" has no property named "file"

I'm probably making a silly mistake here. Can anyone help me with this? Thanks in advance..
