Neither script produces error messages. I added some debugging statements inside prefs.pm so I could see the execution flow (and fixed the newval statement):

pref.pm
package prefs;

use strict;

use Config::IniFiles;
our @ISA = qw( Config::IniFiles );

sub new {

   my $self = shift;
   my $class = (ref $self) || $self;

   print "creating $class\n";

   my $fname = 'fubar.ini';

   my $obj;

   if (-f $fname) {
      $obj = $self->SUPER::new( -file => $fname );

   } else {
      $obj = $self->SUPER::new();
      $obj->SetFileName( $fname );
      $obj->newval('fubar', 'var1', 'default');
   }

   return bless($obj, $class);
}

sub DESTROY {

   my $self = shift;

   $self->RewriteConfig();

   print "destroying $self\n";

   $self->SUPER::DESTROY(@_);
}

1;

I am using Perl 5.8.6 on Win32 (Windows XP) with Config::IniFiles 2.38. I am able to reproduce the same problem on Solaris 8 with Perl 5.8.0 and Config::IniFiles 2.38.
