net-ssh-w32perl stdout hangup problem

[lemire1]

I'm running ActivePerl 5.8.6 build 811 and have been trying to get a
simple script using net-ssh-w32perl (0.05) to run on a Windows XP SP1
platform. I suspect there is an issue with stdout for the following
reason.

(1) I can run the following code without any problem:
=> as long as any stdout gets redirected.
================================================
my($host, $username, $new_password, $old_password);
$host = 'xxx.xxx.xx.xxx'
$username = 'blah';
$old_password = 'secret';

use strict;
use Net::SSH::W32Perl;

## Create a Net::SSH:erl object and login to the remote host.

my %args;
$args{debug} = 1;
$args{protocol} = 2;

my $ssh = new Net::SSH::W32Perl($host, %args);
$ssh->login($username, $old_password);
my ($stdout, $stderr, $exit) = $ssh->cmd('ls > /tmp/foo.out',"\n");
=========================================================

(2) As soon as I change the last line to this, it hangs:

my ($stdout, $stderr, $exit) = $ssh->cmd('ls',"\n");

(3) This is the output I receive:

=======> Hangs Here.

When it runs OK (with the stdout redirect) I get this:

Sending command: ls

channel 1: send eof
channel 1: open confirm rwindow 131071 rmax 32768

channel 1: close_write
channel 1: send close

channel 1: rcvd close

=======> script exits normally

I would appreciate any help!! I've probably spent 10 hours so far just
getting all the requisite modules in place, then uninstalling and
re-installing Active Perl just to be sure something wasn't corrupted.

Thanks
