[gtkmm] simple libglademm program barfs telling me to call g_type_init()

[Nick Nolan <hellish comcast net>]

I'm fooling with glade and libglademm and I have a very simple program that barfs with the 
following error:

hellish localhost src $ ./a.out 

(process:2166): GLib-GObject-CRITICAL **: gtype.c:1871: initialization assertion failed, use g_type_init() prior to this function
Segmentation fault


does anyone know what this means? I know g_type_init() is a GTK+ and not OOPified version 
of some function but I do not know what what it is supposed to do or why I should be calling
it. here's the source:

#include <libglademm.h>

int main(int argc,char *argv[])
{
  Glib::RefPtr<Gnome::Glade::Xml> refXml = Gnome::Glade::Xml::create("gic2.glade");
}

Just in case it has anything to do with my .glade file I'll include that too:
