I have been editing a small script to get the hashes to work for a larger script. So far, I have been getting the error: Reference found where even-sized list expected at ./idv1csv line ---. The "---" represents one of many lines. This script retrieves MP3 information and outputs the hash/value pairs to the screen. Or is supposed to. When running without warnings or strict, it happily produces empty hashes and clean output (wrong). I placed a lot of debugging in the script, but here is what I have:

#! /usr/bin/perl
# (above should be "perl -s" for parameters)

use strict;
use warnings;
use MP3::Info;

foreach my $file (`ls *.mp3`) {
    chomp $file;
    print "$file\n";
    my %info = get_mp3info($file);
    my %tags = get_mp3tag($file);

    foreach my $key (keys %info) {
       my $value = $info{$key};
       print __LINE__, "\t $key = $value\n";
    }
    print __LINE__, "\t Time: $info{TIME}\n";

    foreach my $key (keys %tags) {
       my $value = $tags{$key};
       print __LINE__, "\t $key = $value\n";
    }
    print __LINE__, "\t Title: $tags{TITLE}\n";
}

The output on a console looks like this for one MP3 file:

02_-_Too_Close_To_The_Sun.mp3

ANy help as to why I get this error (Reference found where even-sized list expected) is appreciated. That might help me figure out the other errors, if there is any left.
