GType GValue has not been registered with GPerl at C:/msys64/mingw64/lib/perl5/site_perl/Gtk3.pm

Whenever I run a program to put something into a ListStore, I get the error below:

internal problem: GType GValue (68374864) has not been registered with GPerl at 
C:/msys64/mingw64/lib/perl5/site_perl/Gtk3.pm line 1329.


For Example:

This Simple Program Will Trigger The Error:

use strict;
use warnings;

use Gtk3 '-init';
use Glib 'TRUE', 'FALSE';

my @data = (TRUE, 42, 'Data...');

create_liststore_with_data();

sub create_liststore_with_data  {
    my $lstore = Gtk3::ListStore->new('Glib::Boolean', 'Glib::Uint', 'Glib::String');

        my $iter = $lstore->append();

        $lstore->insert_with_values( $iter,
                0, $data[0],
                1, $data[1],
                2, $data[2] );
}


Adding The Following Line to The BOOT: Section of Glib/GBoxed.xs:

gperl_register_boxed (G_TYPE_VALUE, "Glib::Value", &gperl_value_from_sv);


Seems to fix it.

Patch needed?

Thanks.
