GType GString is not registered with gperl at Glib/Object/Introspection.pm

[Emmanuel Rodriguez <emmanuel rodriguez gmail com>]

Hi,

I'm having some troubles to handle GString types through
Glib::Object::Introspection. Whenever I try to access GString type I
see the following error printed at the console:

*** unhandled exception in callback:
***   GType GString (156083704) is not registered with gperl at
/usr/local/lib/perl/5.12.4/Glib/Object/Introspection.pm line 57.
***  ignoring at /usr/local/share/perl/5.12.4/Gtk3.pm line 104.


The following example (also available in attachment) reproduces the error:

#!/usr/bin/env perl

use strict;
use warnings;

use Gtk3 -init;
use Gtk3::WebKit;

sub main {
    my ($url) = @ARGV;
    $url ||= 'http://www.google.com/';

    my $view = Gtk3::WebKit::WebView->new();
    $view->signal_connect('notify::load-status' => sub {
        return unless $view->get_uri and $view->get_load_status eq 'finished';

        # webkit_web_data_source_get_data returns a GString which causes Perl to
        # generate the following error message:
        # *** unhandled exception in callback:
        # ***   GType GString (177313392) is not registered with gperl
at /usr/local/lib/perl/5.12.4/Glib/Object/Introspection.pm line 57.
        # ***  ignoring at /usr/local/share/perl/5.12.4/Gtk3.pm line 104.
        my $data = $view->get_focused_frame->get_data_source->get_data;

        Gtk3->main_quit();
    });
    $view->load_uri($url);

    my $window = Gtk3::OffscreenWindow->new();
    $window->add($view);
    $window->show_all();

    Gtk3->main();
    return 0;
}
exit main() unless caller;
__END__

In the past I was able to access GString without problems. What should
I do in order to register the GString type with Perl?
