如何在Pygi中使用Xfce小部件？

Question

I've been playing around with pygi recently, trying to put together a mixer plugin for xfce, but when I try to load the GtkBuilder file from python it doesn't recognize the XfceTitledDialog (which I'm trying to use for the configuration dialog).

Is there something special I need to do to use xfce widgets?

Here's what I've got so far:

Python 2.7 (r27:82500, Aug 07 2010, 16:54:59) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from gi.repository import Gtk,Gdk
>>> builder = Gtk.Builder()
>>> builder.add_from_file('xfvol.ui')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.7/site-packages/gtk-2.0/gi/types.py", line 40, in function
    return info.invoke(*args)
RuntimeError: Invalid object type `XfceTitledDialog'

Changing XfceTitledDialog to GtkDialog makes it work, but it's the wrong widget.
The widget is available and appears to work in Glade.

Try setting some shell environment variables that glade needs.

GLADE_PIXMAP_PATH=/usr/share/glade3/pixmaps
GLADE_CATALOG_PATH=:/usr/share/glade3/catalogs
GLADE_MODULE_PATH=:/usr/lib64/glade3/modules
LIBGLADE_MODULE_PATH=/usr/lib64/libglade/2.0

Make sure those are the right paths on your system and the the xfce modules are in there.
