Thanks to Igor and you for fixing this. The impact did not appear obvious to me at first, to be honnest! I'm queuing the patch for next release.
BTW, I've noticed your other patch for 2.2.26, but it's not worth wasting time on it, as 2.2 has remained unmaintained for years now and people are really discouraged from using it as many holes have never been fixed there.
