Symfony 1.4 I get the wrong values in app.yml - plugins

Question

Obviously it is not that simple. Let's start from the beginning: I'm working on a shared project and yesterday I've been asked to add the plugin mgI18n. I followed the readme file step by step, but when it came down to run the command line to create the table used by the plugin, I got this:
database "" does not exists
I searched it, and I found out that sfConfig::get('app_mgI18nPlugin_connection'); returned an empty value. It was weird, because I've done every step right, setting the value in my app.yml and clearing symfony cache, so I logged sfConfig::getAll(); and found out that the only values for 'app_' stored here were the ones from the file app.yml in the plugin folder of kdDoctrineGuardFacebookConnectPlugin. I've already tried removing that file and clearing the cache, obtaining only to lose these values.
Here is the file contents:
project/apps/frontend/config/app.yml
all:
#other values
facebook:
appId: yyy
secret: yyy
cookie: true
script_lang: fr_FR
perms: email
mgI18nPlugin:
connection: doctrine
cultures_available:
fr: Français
en: English
it: Italiano
de: Deutsch
project/plugins/kdDoctrineGuardFacebookConnectPlugin/config/app.yml
all:
facebook:
appId: xxx
secret: xxx
cookie: true
script_lang: fr_FR
perms: email
and this is what I get when I log sfConfig::getAll(); :
array('app_facebook_appId' => 'xxx',
'app_facebook_secret' => 'xxx',
'app_facebook_cookie' => true,
'app_facebook_script_lang' => 'fr_FR',
'app_facebook_perms' => 'email',
)
Why the values for the main app.yml are not loaded? How do I correct this behaviour?
Thank you all in advance for your help, if you need more specifics I'll glady add them

If I understood you well you are in a command line task context (some sfTask). Symfony tasks by default do not run in application context. In most cases just call your task as
./symfony namespace:name --application=frontend
and you will have your configs.
If it is your own task just add it an option with default value in your configure method:
$this->addOptions(array(
new sfCommandOption('application', null, sfCommandOption::PARAMETER_REQUIRED, 'The application name', 'frontend'),
...
)
Plugin settings are loaded correctly, because plugins are configured per project not application (you enable them in ProjectConfiguration, not generated frontendConfiguration class)
