Yes, we need to get a fix into 6.3 as well.
The 'issue' with a backport is noted in the IMPORTANT NOTE above.
My concern is that adding cc:stable will have it automatically picked up
and this would make things worse than they are in 6.3.
My 'plan' was to not add the cc:stable, but manually create a patch for
6.3 once this goes upstream. Honestly, I am not sure what is the best
way to deal with this. I could also try to catch the email about the
automatic backport and say 'no, use this new patch instead'.
