Thanks, in that case things aren't as clear as I had assumed
when writing my previous email.

If the problem only occurs after 4051f68318ca9 then I think
it is fine to use that commit in the Fixes tag.

Although I do wonder if commit 4051f68318ca9 is backported,
will this patch (once accepted) end up being backported far enough?
