Package: zlib1g
Version: 1:1.2.3.4.dfsg-1
Severity: grave
Justification: renders package unusable

Hi,

It seems that zlib1g 1:1.2.3.4.dfsg-1 broke something.

To reproduce: In a clean minimal unstable chroot (amd64), install man-db
=> hangs on "Setting up man-db (2.5.6-4) ...
Building database of manual pages ..."

If, in a clean minimal chroot, I install zlib1g from testing first, then
install man-db, it works fine.

My guess is that it is related to the fixing of #301283.
