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!
