Remind your editors to disable user accounts instead of deleting them!

Did an eZ Publish 4.4 upgrade today and got a "Data Error" problem in the "Sub items" window. I quickly checked the usual suspects of rewrite rules and PHP-CGI setup first -- no issues.

The PHP error log showed:
PHP Fatal error: Call to a member function attribute() on a non-object in ezpublish-4.4.0/extension/ezjscore/classes/ezjscajaxcontent.php on line 252

This particular line of code returns the object's last modifier user. The general eZ Publish rule since the beginning of time has been "don't remove a user account unless you know they haven't created or edited any objects", but only since 4.4 does this cause the crippling problem of an empty "Sub items" window. In this case, the client had innocently deleted a main editor user object (without a trace in the trash).
The fix is relatively straightforward: in the table ezcontentobject set owner_id to another user (or a re-created user) if it's "0"; in the table ezcontentobject_version set creator_id to another user (or a re-created user) if it's "0".
