Personally, I'm happy with that dependency.

That was required, but there might have been a cleaner way to do
it... Without that, the pygobject 'magic' doesn't tie in all the GDK
pixbuf methods with the pixbuf object that is returned from C to
Python-space. Maybe I can do that init step somewhere else.

If we're going to only build the python module if GTK is around, I'm
sure we can depend fully on pygobject too.

It looks like the swig run didn't include this part:

#ifdef HAVE_GDKPIXBUF
#ifdef HAVE_PYGOBJECT
%typemap(out) gpointer itdb_thumb_get_gdk_pixbuf {
  $result = pygobject_new((GObject *)$1);
  g_object_unref($1);
}

%typemap(in) gpointer pixbuf {
  $1 = GDK_PIXBUF(pygobject_get($input));
}
#endif
#endif

so one of those ifdef's failed?
