I just uploaded an NMU, and I am cloning the part I did not fix into
a new bug.

Fixed in my NMU based on the patch from Andreas Beckmann.

This is the contents of the cloned bug.
Sorting out prelude-admin is non-trivial:
- libprelude2 cannot depend on the package it gets moved to,
since this would create a circular dependency
- some rdeps of libprelude2 will need a dependency on this
new package

Fixed in my NMU.
