Could it simply be that you forgot to gtk_widget_show() the label ?
libglade doesnt do anything sinister that I know of to tables, the fact
that you are modifying a constructed table may change things, could
your widget be shown underneath another widget already on the table ?

No there is no safe object copying mechanism in place, nor is there a
recursive
one, better to use the "root node" argument like you mentioned to build
templates
and just modify them as needed while adding to the interface.
