Few possible reasons:
- if gtk+-2.16, then Gtk2::AboutDialog have get_name() overridden.
- if gtk+-2.18 or 2.20 (can't remember), then its a gtk+ and not gtk2-perl issue.

You can use:

  $widget->get('name')

 in general to make sure you get the widget name property, but for builder objects with later gtk+ versions, 
its not really a Gtk2::Widgets, and the name property usually returns an empty string, so you need to use:

  $builder_object->Gtk2::Buildable::get_name

Hope that helps.
