Bug#231339: [kregexpeditor] Old package libkregexpeditor not removed on upgrade

[Frans Pop <aragorn@tiscali.nl>]

Package: kregexpeditor
Version: 4:3.2.0-0woody1
Severity: serious

The package kregexpeditor in the backports for Woody on download.kde.org has:
   Version: 4:3.2.0-0woody1
-> Replaces: libkregexpeditor
   Provides: libkregexpeditor
   Depends: kdelibs4 (>= 4:3.2.0), ...
-> Conflicts: libkregexpeditor

However, when I updated from the 3.1.4 backports, the old package 
libkregexpeditor_4:3.1.4-0woody1 was not removed and is now shown as obsolete 
in dselect.

Maybe Replaces and Conflicts should be 'libkregexpeditor (<4:3.2)'?

I successfully manually deleted the old package with 'dpkg -r 
libkregexpeditor'.
