Running cap production deploy --trace gives me:

Which seems entirely confined to gem code. Before I open an issue with them (sshkit?), has anyone seen this before?
I use Net::SSH::Config to get the SSH user from my SSH config file. I know that those settings are correct, as I'm able to use them to log into the server.
remote_user = Net::SSH::Config.for('50.198.83.200')[:user] || ENV['USER']
server '50.198.83.200', user: remote_user, roles: %w(app db web)
But I've tried setting the remote user with USER=the_user_name cap, etc. and still get the same error.

My log_level line was incompletely written as
set :log_level
With no second argument.

THX Have a good day.
As far as I can tell, from a few minutes of looking in source-code, this comes from the lack of :application setting in either config/deploy.rb or the environment specific deploy-config file.
We have, for example, just an excerpt of config:
set :application, 'myappname'
set :repo_url, 'git#github.com:org/app.git'
set :deploy_via, :remote_cache
# Default branch is :master
set :branch, :master
The error is thrown, from validate :application do |_key, value| in capistrano, which suggests that application is nil - Which it will be, if the value is unset (see config above).
Can you validate, that you have set :application in the config?

Redmine receiving emails from imap

I have installed Redmine 2.6.1-stable, it works using apache2 and passenger.
I'm trying to receive emails using imap with this two rakes:
this one:
rake -f /opt/redmine-2.6.1/Rakefile --silent redmine:email:receive_imap RAILS_ENV="production" host=smtp.yandex.ru port=465 username=mail#yandex.ru password=pwd ssl=true project=desk folder=INBOX move_on_success=processed move_on_failure=failed no_permission_check=1 unknown_user=accept
And this one:
bundle exec rake redmine:email:receive_imap host='smtp.yandex.ru' username='mail#yandex.ru' password='pwd' port=465 ssl=true starttls=true allow_override=type,project project=desk
And this is log:
** Invoke redmine:email:receive_imap (first_time)

I can't understand what's going on.. Why it does not work properly?
Log /opt/redmine-2.6.1/logs/production.log is empty about this operation.
I recently solved my similar problem with enabling debug on IMAP, so I could see what's happened. To do that;
vim /var/www/redmine/lib/redmine/imap.rb
and after require 'net/imap' add this line:
Net::IMAP.debug = true
It usually relates to the login credentials/method.
You are trying to receive IMAP email from an SMTP server. These are completely different protocols.
Likely you want server imap.yandex.ru, Port 993, with SSL (not starttls).
Settings for IMAP appear to be available at https://yandex.com/support/mail/mail-clients.xml

Rake Task to Restart Heroku Server

I'm trying to create a rake task that restarts my heroku servier. I've found this post, which has helped immensely: http://railspikes.com/2010/2/13/rake-task-for-deploying-to-heroku.
I've cobbled together this rake task, but it's giving me an error. The rake abouts and I get the message:
uninitialized constant Heroku::Command::BaseWithApp.
This is my method.
desc 'restarts the server'
task restart_server: :environment do
require 'heroku'
require 'heroku/command'
user, pass = File.read(File.expand_path("~/.heroku/credentials.txt")).split("\n")
heroku = Heroku::Client.new(user, pass)
cmd = Heroku::Command::BaseWithApp.new([])
remotes = cmd.git_remotes(File.dirname(__FILE__) + "/../..")
remote, app = remotes.detect {|key, value| value == (ENV['APP'])}# || cmd.app)}
if remote.nil?
raise "Could not find a git remote for the '#{ENV['APP']}' app"
end
heroku.restart(ENV['APP'])
end
I'm not sure why it's rejecting Heroku::Command. The app is already live on Heroku, so I know it's Heroku compliant.
Any advice?
EDIT: Here's my stack trace.

Tasks: TOP => db:structure:dump
Any idea on what might be the problem?
Add pg_dump to PATH and it will be fine.

YAML DB won't run due to evaluating nil.each

So this problem is occurring for me on both RHEL5 and OSX Lion. Both environments are running 1.9.2-p290 ruby installed with RVM.
When I run the following command I get the following problem:
[master][~/Sites/boss-mocha] bundle exec rake db:data:load --trace
** Invoke db:data:load (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:data:load
rake aborted!
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each

Tasks: TOP => db:data:load
The YAML being produced by rake db:data:dump appears mal-formed, with spurious "---"s between the "records" list and the actual records.
Removing the inappropriate "---" allows the data to load. I haven't created a pull request for the fix yet, but after tracking it down I noticed someone else reported it as an issue on github:
https://github.com/ludicast/yaml_db/issues/17
In addition, changing the YAML engine as in the link below produces correct output, eliminating the need for editing the file manually (or fixing yaml_db).
rails error, couldn't parse YAML
