Net:SSH problem with open_channel

Description

=begin
It appears that the open_channel method does not always work when used without passing it a block.

Steps to reproduce:

require 'net/ssh'
ssh = Net::SSH.start('system', 'user', :password => 'password')
ch = ssh.open_channel
ch.exec 'ls' do |ch, success|
end

Resultant error:

TypeError: can't convert nil into Integer
from /usr/lib/ruby/site_ruby/1.8/net/ssh/buffer.rb:294:in pack' from /usr/lib/ruby/site_ruby/1.8/net/ssh/buffer.rb:294:in write_long'
from /usr/lib/ruby/site_ruby/1.8/net/ssh/buffer.rb:55:in send' from /usr/lib/ruby/site_ruby/1.8/net/ssh/buffer.rb:55:in from'

from (irb):9

The same does work if open_channel is passed a block, however, like such:

require 'net/ssh'
ssh = Net::SSH.start('system', 'user', :password => 'password')
channel = ssh.open_channel do |ch|
ch.exec 'ls' do |ch, success|
end
end

Also it will work if you run ssh.exec! before running ch.exec:

require 'net/ssh'
ssh = Net::SSH.start('system', 'user', :password => 'password')
ch = ssh.open_channel
ssh.exec! 'ls'
ch.exec 'ls' do |ch, success|
end

This might not be correct place for a Net::SSH bug report. Did you try contacting Jamis ?
