using the api to create an object as described here: https://confluence.ez.no/display/EZP/3.+Managing+Content
will cause the sequence:
<code>
$locationCreateStruct = $locationService->newLocationCreateStruct( $parentLocationId );
$draft = $contentService->createContent( $contentSkeleton, array( $locationCreateStruct ) );
$content = $contentService->publishVersion( $draft->versionInfo );
</code>

to return an error with the exception:

[eZ\Publish\Core\Base\Exceptions\InvalidArgumentException]
Argument '$locationCreateStructs' is invalid: Another Location with remoteId 'a6d8a811e83ed8b5eaba24e3fd087b98' exists

create a test bundle to use the ezpublish/console script attached.
put the attached file in the bundle/Command dir

run with ezpublish/console test:singleItem

each run shows a different hash, so object is not the same.
