Andrea, this bug is just a new filing for https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1370017 which is still not fixed in Trusty. The verification instructions in that bug were wrong, and thus it's marked as "Fix Released" when it's actually not fixed at all.
If it has actually been fixed in vivid, maybe the backported patch missed something?
