libqt3-mt installation conflict

[Hamid <mylists@spils.com>]

Hi
I was trying to setup libqt3 files by:
# apt-get -s -t unstable install libqt3-mt

To me, the message was surprising. apt-get  listed all KDE packages 
(including kdebase) in the "to be removed" section.
Since I used simulation of installation, thanks God, I am happily using 
my KDE 3.1.2 . But I was wondering why this should happen.
And how I can install libqt3-mt. it seems that I DO NOT have any libqt 
installed on my box.

Thanks in advance

Hamid
