I have the same problem, and after some investigation here is what I've found:
- first, I ran "sudo dpkg-reconfigure debconf" and selected KDE as frontend.
- then I ran the same command again, and saw this message:
"debconf: (Unable to load QtCore -- is libqtcore4-perl installed?)"
After some digging, I found the missing packages: libqtcore4-perl, libqtgui4-perl, libqt3support4-perl
Installed them, and this completely broke the updater... Now I get this error when I try to dpkg-reconfigure some package:
Can't call method "setText" on an undefined value at /usr/share/perl5/Debconf/FrontEnd/Kde/Ui_DebconfWizard.pm line 144, <GEN1> line 7.
