what output do you get if you change your print loop to 
foreach my $key ( keys %hash ) 
{
    #print "$key: @{ $hash{$key} }\n"
    print "$key: \n";
    foreach (@{$hash{$key}})
    {
        print $_ , "\n";
    }
}

Does each line get printed correctly, or are the lines garbled as in your old output?
