Special notes for your reviewer:
Suggestions on how to test this:
Without this fix, trying to index a harvested dataset that has a file with a NULL in the storageidentifier filed, dvobject table, results in a failure to index and a stack trace in the log file. (Can provide queries for creating a test case in a db, if needed).
