After upgrading from eZ Publish 5.4.x to ezplatform 2.0.0.2 you get an error in the administration when you click on a location that has a version where the creator was deleted.

Twig_Error_Runtime:
An exception has been thrown during the rendering of a template ("Could not find 'Content' with identifier 'array (
'id' => 0,
'languages' =>
array (
),
'versionNo' => NULL,
)'").

This also happens when you create a new user on a clean ezplatform 2.0.0.2 installation, edit the frontpage with this user and delete the user afterwards. It doesn't matter if the user published the currently active version or any previous one. The error message stays pretty much the same...the only difference is that you can see the 'id' and 'versionNo' of the deleted user.
