Hello Jes,
I have analyzed this issue, and information with this analysis is posted in
a separate thread.
The issue is caused by patch 4ae96c802203.
We have no fix for it at the moment, and if you plan to mark a release
candidate now, it would be good to revert that patch (as Nigel already
mentioned).
Thank you!
