I am unable to reproduce these introspection errors which came from error reporting as we don't have a database schema.

I am going to tag this with topic: introspection error reporting so that someone working on the this part of rust source can check the source code lines which the error is referencing.

Unfortunately we were not collecting the information in our error reporting in a format that allows us to replay the bug. That has changed with 2.19 which should be out next Tuesday.This should allow us to exactly pinpoint the issue.

I'm closing this one now because we cannot act on it.
