Bug 476260 removed storeReadMailInPFC and bug 530618 will fix the UI on trunk, but on branch the UI is trying to access a non-existent property.
As I expect any patch will only be deleting locale lines, it should not matter for branch if the locales leave those lines in. Kairo will probably know (would anyone else?) what happens as to things turning red or not on the locale dashboard so cc'ing - he can always change to deny if need be.
