I am getting crash reports with the following stack trace:

All user crash reports I received come from 10.11.2 beta.

I was able to recreate the crash in my app when running on 10.11.2 beta. I can't recreate the problem on 10.11.1 or 10.10.6.


So far I have no idea where my app triggers this.

Before going on a lengthy hunt, I figured I'd ask here if anybody else has seen problems with Core Data on the latest betas.
