Can you post a script and your software versions?  I can't reproduce  
on my (rather ancient) system with this:

#!/usr/bin/perl -w

use strict;
use Gtk2 -init;
use Gtk2::SimpleList;

my $slist = Gtk2::SimpleList->new ('Stuff' => 'text');

@{ $slist->{data} } = qw(one two three four five six seven);

my @data = @{ $slist->{data} };
@{ $slist->{data} } = @data;


print "Gtk2::VERSION              $Gtk2::VERSION\n";
print "Gtk2::SimpleList::VERSION  $Gtk2::SimpleList::VERSION\n";
print "Gtk2->GET_VERSION_INFO     ".join(".",Gtk2- 
>GET_VERSION_INFO)."\n";
print "Gtk2->get_version_info     ".join(".",Gtk2- 
>get_version_info)."\n";

----------------------------------

Gtk2::VERSION              1.080
Gtk2::SimpleList::VERSION  0.15
Gtk2->GET_VERSION_INFO     2.4.0
Gtk2->get_version_info     2.4.14
