Ingesting islandora:sp_basic_image objects via command-line drush results in confused and incomplete objects and derivatives.
Instead of the original image being stored in the OBJ datastream, it's being stored in the TN datastream in its entirety. No true TN derivative is produced.
Additionally, no TECHMD datastream is produced, nor is a MEDIUM_SIZE datastream derivative generated.
RELS-EXT, MODS, and DC ingest successfully via command-line batch.
