This is most likely because when copying the {{<CONFLUENCE_HOME>}} and the database over from production to test on the test server, they were copied over from a live instance and are slightly out of sync, hence the attachment does not exist in the home directory though it does in the database. Point of the story is, we shouldn't be throwing NPEs :)
