[Glade-users] GtkWarning: gtk_button_box_set_child_secondary: assertion `child->parent == GTK_WIDGET (widget)' failed

[gerald.britton at gmail.com (Gerald Britton)]

Sure, but dups are OK in a glade file as long as the widgets are unique
within toplevels.  (at least I think so and glade-3 seems to support the
notion.)  So that can't be the error.  What is a secondary?  If I knew that
I'd know better where to look.
