The dist-upgrade problem is affecting lots of us because "the debian team has been compiling the whole backend of kde, kdelibs has just been updated, so most of its backend is done, only the frontend applications are left and can be expected within a few weeks (my best guess). You are advised not to upgrade until this is out as it could possibly break kde. please hold off on upgrades until 3.4 is fully complete."
