From what I can see, mozilla only depends on zlib >= 1:1.1.4, which should be satisfied by zlib 1:1.1.4-16 currently in testing, and I would believe mozilla could go in now.
Still, update_excuses says mozilla is invalidated by that dependency. I also note that one of my own packages, openbox, are (amongst other tings) stalled by libxml2. Yet, I am quite certain the version in testing fully satisfies openbox' dependency. Could someone explain this behaviour to me? -- Tore Anderson
