Bug#539031: libgnome2-perl: Unknown internal child: dock

[x]

Package: libgnome2-perl
Version: 1.042-2
Severity: normal

i created a ui xml file with glade-3, using a GNOME App Widget. i converted it with gtk-builder-convert. when reading the gtk-builder xml file with Gtk2::Builder::add_from_file(), i get an error saying 'Unknown internal child: dock'.

i guess this is some sort of symbol/build issue?
