Right, d-r-u in trusty uses utopic's, utopic uses vivid's, etc. (Well, more to the point, they use the tarball for the target series).
So, when you were testing utopic, you were actually testing vivid, and when testing trusty, you're testing pre-fix utopic.
In light of that general annoyance in reproducing and validating this, I think I'll just do a by-hand validation of the 1-line patch itself and release, and you can reopen the bug if it proves to still be broken after the tarballs are updated.
