Checking that the bundle is autoloaded: FAILED - symfony

Question

I cannot create a bundle. I'm getting "Checking that the bundle is autoloaded: FAILED" which never used to happen before until now. Steps below always worked until today.
Any solutions?
To setup Symfony2:
I downloaded: Symfony_Standard_Vendors_2.4.5.zip
I unzipped under: /var/www/html/local/three. three is the main folder.
I set the permissions:
desktop#ubuntu:/var/www/html/local/three$ sudo chown desktop -R app/logs
desktop#ubuntu:/var/www/html/local/three$ sudo chown desktop -R app/cache
desktop#ubuntu:/var/www/html/local/three$ sudo chmod 777 -R app/cache
desktop#ubuntu:/var/www/html/local/three$ sudo chmod 777 -R app/logs
This URL works fine: http://localhost/local/three/web/app_dev.php
To create my bundle:
desktop#ubuntu:/var/www/html/local/three$ php app/console generate:bundle --namespace=Myblog/PublicBundle
Welcome to the Symfony2 bundle generator
In your code, a bundle is often referenced by its name. It can be the
concatenation of all namespace parts but it's really up to you to come
up with a unique name (a good practice is to start with the vendor name).
Based on the namespace, we suggest MyblogPublicBundle.
Bundle name [MyblogPublicBundle]:
The bundle can be generated anywhere. The suggested default directory uses
the standard conventions.
Target directory [/var/www/html/local/three/app/cache/dev/../src]:
Determine the format to use for the generated configuration.
Configuration format (yml, xml, php, or annotation): yml
To help you get started faster, the command can generate some
code snippets for you.
Do you want to generate the whole directory structure [no]? yes
Summary before generation
You are going to generate a "Myblog\PublicBundle\MyblogPublicBundle" bundle
in "/var/www/html/local/three/app/cache/dev/../src/" using the "yml" format.
Do you confirm generation [yes]? yes
Bundle generation
Generating the bundle code: OK
Checking that the bundle is autoloaded: FAILED
Confirm automatic update of your Kernel [yes]? yes
Enabling the bundle inside the Kernel: OK
Confirm automatic update of the Routing [yes]? yes
Importing the bundle routing resource: OK
The command was not able to configure everything automatically.
You must do the following changes manually.
- Edit the composer.json file and register the bundle
namespace in the "autoload" section:

Answer 1

Solved:
Problem is to do with line:
Target directory [/var/www/html/local/three/app/cache/dev/../src]:
I don't understand why it is suggesting cache path. Old days it was always automatically suggesting src directory instead. I've checked my logs that's why I know. Anyway change it to:
/var/www/html/local/three/src
Done!

Answer 2

This is a known issue now, I guess it will be fixed on the next version
https://github.com/symfony/symfony/issues/10972
https://github.com/symfony/symfony/pull/10999
https://github.com/symfony/symfony-standard/issues/659
for now when the generate:bundle displays this:
The bundle can be generated anywhere. The suggested default directory
uses the standard conventions.
Target directory:
-- /type/your/directory/src here
