I want to modify the primary message widget so I can select and copy the text.

This fails: Gtk-CRITICAL: 08:51:12.080: gtk_label_get_label: assertion 'GTK_IS_LABEL (label)' failed

So the primary message widget isn't a Gtk::Label. How do I determine what it is?

Is your dialog a MessageDialog? If it is, use get_message_area() instead of get_content_area().
