It seems there is invalid arguments passed through the CriterionLogicalAnd constructor for the copySubtree method of the location service.

https://github.com/ezsystems/ezpublish-kernel/blob/master/eZ/Publish/Core/Repository/LocationService.php

line 26:

use eZ\Publish\API\Repository\Values\Content\Query\Criterion\LogicalAnd as CriterionLogicalAnd;

line 143:

            $query = new Query(
                array(
                    'limit' => 0,
                    'filter' => new CriterionLogicalAnd(
                        new CriterionSubtree( $loadedSubtree->pathString ),
                        new CriterionLogicalNot( $contentReadCriterion )
                    )
                )
            );

If we check to the LogicalAnd criterion class:
https://github.com/ezsystems/ezpublish-kernel/blob/master/eZ/Publish/API/Repository/Values/Content/Query/Criterion/LogicalAnd.php

and the LogicalOperator criterion class:
https://github.com/ezsystems/ezpublish-kernel/blob/master/eZ/Publish/API/Repository/Values/Content/Query/Criterion/LogicalOperator.php

We can see that the constructor attemps an array as a first argument.
In the location service we put two arguments (CriterionSubtree and CriterionLogicalNot).

The consequence, for some case we get the current error:

PHP Catchable fatal error: Argument 1 passed to eZ\\Publish\\API\\Repository\\Values\\Content\\Query\\Criterion
LogicalOperator::__construct() must be an array
