Bug ID: 1273668
           Summary: to_string() appends 'undef' to array attribute
           Product: Fedora EPEL
           Version: epel7
         Component: perl-Exception-Base
          Severity: low
          Assignee: paul@city-fan.org
          Reporter: jim@apnic.net
        QA Contact: extras-qa@fedoraproject.org
                CC: paul@city-fan.org, perl-devel@lists.fedoraproject.org
Description of problem:
Invoking to_string has the side effect of appending 'undef' to an array
attribute.
Version-Release number of selected component (if applicable):
perl-Exception-Base-0.2500-1.el7.noarch.rpm
perl v5.16.3
How reproducible:
Always
Steps to Reproduce:
Can reproduce with this perl script:
#!/bin/perl
use warnings;
use strict;
use Data::Dumper;
use Exception::Base
    'MyException', => {
        message => 'Validation error',
        has     => [ qw(class errors) ],
string_attributes => [ 'message', 'class', 'errors' ]
    };
eval {
    MyException->throw(
            class  => __PACKAGE__,
            errors => ["error 1", "error 2", "error 3"]
        );
};
my $exception = $@;
print( Dumper($exception->errors()) . "\n");
$exception->to_string();
print( Dumper($exception->errors()) . "\n");
Actual results:
Can see an additional 'undef' in the array returned after invoking to_string();
Expected results:
The returned array should be the same as when thrown.
