TYPO3 Core

Using a T3D file with a structure as below, containing sys_file_reference records with missing files, will make the T3D importer fail because if missing array indices and assumptions that will fail, and not import any content. The core should more "gracefully" fail on this to at least be able to import partial data (with error messages)

Errors yielded were:
