libglade-WARNING **: could not find a parent that handles internal children for `vbox'

[Lars Luthman <larsl users sourceforge net>]

I'm trying to build a program (not mine) that uses libglademm. It
compiles and links fine, but when I try to run it and it tried to load
the Glade file I get these messages:

All the widgets that are "not found" exist in that Glade file, inside a
Table inside a VBox inside a FileChooserDialog which is loaded using
Xml::get_widget_derived(). If I comment out this call to
get_widget_derived() the program runs fine until it tries to use that
widget.

I searched google and found a similar problem:
http://bugzilla.gnome.org/show_bug.cgi?id=155738

But this is supposed to have been fixed in the latest libglademm. I was
using libglademm 2.4.1, so I upgraded to 2.6.0 - but the problem is
still there.

Does anyone have any idea how to fix this? Other people have built and
used this program successfully using libglademm 2.4.1 (although on
different distributions - I'm using Mandrake).

The program: http://savannah.nongnu.org/projects/om-synth
The Glade file:
