I think it would be nice to backport this patch. https://git.reviewboard.kde.org/r/115271/
See also bug 502440.
There's no point backporting to 4.11.5, because we would have to make a revision bump and wait adequate time before stabilising it. We are ready to stabilise 4.11.7 (which contains the fix) soon, see bug #504210.
Well OK, makes sense.
