We are doing test upgrade of Moodle from 2.8.5+ to 2.9+ and got the following error during upgrade:

We didn't see this during our last test upgrade (which would have been to 2.9.0), but I'm not sure if that means the code was integrated in the last few weeks, or that the flaw in our dataset is new, as each time we do the test upgrade we start with a fresh snapshot of prod.
I haven't had time to dig into it yet.
