Please provide a full description of the user-visible runtime effects
of the bug (always always).

I'll add the cc:stable (per your comments in the [0/N] cover letter),
but it's more reliable to add it to the changelog yourself.

As to when I upstream this: don't know - that depends on the
user-visible-effects thing.
