It looks like this is due to a null SystemMetadata.size entry in the underlying table. I'm not sure how a null could get in there, unless there was an error when registering the SystemMetadata record.

wasn't able to replicate this, but will keep an eye out. There's been quite a lot of churn around the DB tables, so it's possible null values have crept in during development upgrades to the systemMetadata table.
