This file defines in line 14 a ../libraries/import.php dependencies, which is not included in the package.

It's included! If you speak German: Why the error occurs was discussed yesterday in a German forum:
http://www.joomlaportal.de/joomla-3-x-installation/323446-fatal-error-class-joomla-application-abstractapplication-not-found.html#post1610912

I could reproduce the explanation by debugging and the guy is right.

But if the file is still needed I don't know.

I don't believe you call the keychain file directly, which is why your getting an error. Most Joomla php files are not intended to be called directly. Keychain is a library class definition file which gets called by another file to implement and use the methods. Keychain "provides is a way to load data from, and store data to an encrypted data source."

I am aware that the file should not be called directly. The problem is that
they can be called directly! And outputs may a Fatal Error!

They why are you asking for the file to be removed? I suggest changing your issue title to reflect your issue.

Thanks for your answer. I think the file is no longer needed for Joomla.
The Class Keychain is to my knowledge fully integrated into the platform.

Keychain "provides is a way to load data from, and store data to an encrypted data source." It is absolutely needed anytime the application, or a 3rd party extension needs to load or store data to an encrypted data source.

As far as I can tell the CMS does not currently utilize JKeychain from the framework, but there are 3rd party extensions which do.

Tested following the supplied steps, I can confirm this issue. (error listed in the server error logs)

PHP Fatal error:  Class 'Joomla\Application\AbstractApplication' not found in /libraries/joomla/application/base.php on line 23

Seems that in this instance the library application base class is failing to load the Joomla\Application\AbstractApplication namespace and class. I think it's likely accessing the bin/keychain.php file directly results in the application losing track of the root path and it's looking in the wrong place to find the library files.

The JKeychain class is integrated in the platform. The bin/keychain.php
file is a CLI utility to work with keychain objects. So the file is still
useful and probably just needs updated with the proper CLI bootstrap for
the CMS.
