Hell, right, there was an update! Ok, and it's the same thing here: 
Fortunately, on another server the update has not been applied. And on 
this server my config still works.
I so tried to downgrade my problem server to *deb7u1, but that did not work.
Appearently, the problem occurs since updating to *deb7u2.
