Side note. The patch is already merged to 'next', so if you can try it to
see if it fixes your issue, we are hopefully in a good shape.
Side note2. I applied the patch with "git-am -3" to 'master', which reused
the recorded resolution I previously had to make when I merged the topic
to 'next' to resolve the conflict fully. This patch was created by taking
the diff between that result and 'master'.
