I'm using CGI.pm, v 2.80 to create popup_menus from DBI queries. For some reason, the "-labels=>" option in popup_menu isn't working- I'm not getting the IDs as the values.

sub create_cat_list{
    my ($type,$dbh)=@_;
 my $cat=$dbh->prepare("select ${type}_cat,${type}_id from ${type}_cat
+ order by ${type}_cat");
    $cat->execute();
    my @list;
    my %hash;
    while(my ($catval,$id)=$cat->fetchrow_array()){
    push @list, $catval;
    $hash{$id} = $catval;
    }
    $cat->finish();
    return [ \%hash,\@list  ];
}

## SNIP
    my $l1=create_cat_list('l1',$dbh);

    $output.=$q->popup_menu(-name=>'l1_cat',-values=>$l1->[1],-labels=
+>$l1->[0]);

The popup_menu doesn't end up with the -labels being applied to it. Using Data::Dumper, the hash ref comes through from create_cat_list() fine. Is this a bug in CGI 2.8.0? I completely don't understand what's going on. Data::Dumper output of create_cat_list() is below. 

   $VAR1 = [
          {
            '1' => 'Canadian Paper Money',
            '2' => 'US Coins',
            '3' => 'US Paper Money',
            '4' => 'Supplies',
            '5' => 'Canadian Coins'
          },
          [
            'Canadian Coins',
            'Canadian Paper Money',
            'Supplies',
            'US Coins',
            'US Paper Money'
          ]
        ];

and here's the HTML being output. 
<select name="l1_cat">
<option value="Canadian Coins">Canadian Coins</option>
<option value="Canadian Paper Money">Canadian Paper Money</option>
<option value="Supplies">Supplies</option>
<option value="US Coins">US Coins</option>
<option value="US Paper Money">US Paper Money</option>
</select>

Maybe I'm missing the obvious, but what the heck is going on here?
