Hello Kenneth,

I rewrote my code to use Gtk::Builder::create_from_file() logic, but as
result I get:

BuilderError: Invalid root element: 'glade-interface'

My glade file starts like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE glade-interface SYSTEM "glade-2.0.dtd">
<!--Generated with glade3 3.4.5 on Mon Mar  1 22:21:23 2010 -->
<glade-interface>
  <widget class="GtkWindow" id="Application">
    <property name="visible">True</property>
    <property name="title" translatable="yes">Hello World!</property>
    <property name="default_width">500</property>
    <property name="default_height">400</property>
...

Any ideas about that problem?

regards
