Comment 6 Ross Burton 2025-06-12 15:09:43 UTC 
This hasn't happened for a while.  Moving to 5.3 but it is possible that better locking has been backported so we should close it in a few months if it doesn't replicate.
Comment 7 Ross Burton 2026-01-29 22:30:58 UTC 
Posted the backport of the "rebase before pushing" patch for the kirkstone branch, hopefully will stop this rare race.
Comment 8 Ross Burton 2026-02-26 16:10:30 UTC 
Should be fixed for kirkstone in bb08d2608471e8cb48e84058a14e77705529093b.
