You don't really need to design a message dialog in glade, because
there is nothing to design.  gtk.MessageDialog is already designed,
you just need to supply the parameters.  The message text is defined
at construction

Try this (for pygtk-2)

import gtk
dialog = gtk.MessageDialog(
    parent         = None,
    flags          = gtk.DIALOG_DESTROY_WITH_PARENT,
    type           = gtk.MESSAGE_INFO,
    buttons        = gtk.BUTTONS_OK,
    message_format = "Your message here")
dialog.set_title('Error!')
dialog.connect('response', lambda dialog, response: dialog.destroy())
dialog.show()
gtk.mainloop()

If you use this code from within some widget, you may want to set the
parent to the calling widget, which will automatically
set_transient_for for you.

However, that dir on the object returned nothing is suspicious.
MessageDialog inherits from Dialog has many many methods.  If you do
dir(dialog) in the example above, you will see them.  In glade, if you
call gtk.glade.XML.get_widget on a nonexistent widget, it will return
None.  Is it possible you are working with None here?
