problem with the upgrade of python-qt4 of this morning ?

[maggsimo at gmail.com]

good morning kubuntu developers,
i'm an italian user of kubuntu.

i have installed kubuntu karmic and i have upgraded kde 4.3 to kde 4.4 with 
kubuntu-backport-ppa two days ago.

This morning i have tried to upgrade kubuntu because i see the new package 
python-qt4, but:


@laptop:~$ sudo apt-get dist-upgrade
[sudo] password for simone:

  update-manager-kde update-notifier-kde usb-creator-kde userconfig


I seguenti pacchetti saranno aggiornati: //... because it want upgrade this
  python-qt4 python-qt4-dbg python-qt4-dbus python-qt4-dbus-dbg

apt try to remove a lot of packages, it's normal or it's a bug?

sorry for my bad english....
