I believe the idea was not that 0.4.2+ fixed it, but to be conservative in how
we apply it.

I'm probably ok either way, though we should really try to get this fixed in
upstream and stop hacking around them. So I wonder if it wouldn't be better to
set this again to the latest-known-working version, so we get another reminder
that we need upstream to fix it.

BB:approve

(Or maybe tweak)
