The following commit has been merged in the piatti branch:
commit 1adc18cdd62216c03064bcd0fb2fdb20eb22cfc4
Author: Andreas Beckmann <debian at abeckmann.de>
Date:   Tue Apr 17 23:00:29 2012 +0200

    only newest version is a candidate
    
    Packages files may contain several versions of the same package and
    are in unspecified ordering. This may happen especially for arch:all
    packages.
    Discard all duplicate package entries but the *newest* version while
    reading Packages files. (Up to now the *last* entry was used, but
    this is not neccessarily the installation candidate, i.e. the newest.)
