Bug#844315: tzdata version breaks dist-upgrade leaving version from oldstable security installed

[Marcel Meckel <debian@thermoman.de>]

I like my systems to have packages from stable and stable security only.
So when I do a dist-upgrade and remove old/outdated/not needed packages
I expect to have all remaining packages to be from stable.

tzdata - although with a newer version - being stuck on oldstable,
is not expected.

It doesn't break anything in terms of "something doesn't work" but more
in terms of "it simply shouldn't be this way".

So, I'm with you - "critical" might not be the appropriate severity 
here.
