What exactly did it do?
Let's break it down into pieces. On my system:
dpkg --status kdelibs4 | awk '/^Version:/{print$2}'
4:3.3.2-6.1
So my version of kdelibs4 is 4:3.3.2-6.1 (sarge version). By saving
that in a shell variable I can use it later.
KDEVER=$(dpkg --status kdelibs4 | awk '/^Version:/{print$2}')
echo $KDEVER
4:3.3.2-6.1
The grep-status command is actually in the grep-dctl package. It is
not required to be installed but several other packages do depend upon
it so it is likely to be installed. This is mostly what I would guess
would go wrong. You may need to install it.
apt-get update
apt-get install grep-dctrl
grep-status -F Version $KDEVER | grep-dctrl -F Status -s Package -n -r "^install"
This is the same as specifying the version inline. But by using the
variable it would dynamically be whatever it is on your system.
grep-status -F Version 4:3.3.2-6.1 | grep-dctrl -F Status -s Package -n -r "^install"
kdelibs
kdelibs4
kdelibs-bin
kdelibs-data
...and on and on...
Actually I don't personally use KDE. So that list above really is all
that is installed on my sytem. But I administer many other machines
which do have KDE installed and on those the list goes on and on.
But I see the problem now while testing this out. Prior to the
release of Sarge all of the KDE packages had the same version. That
is they were all 4:3.3.2-1 or some such. But I can now see that there
are various different versions such as the above 4:3.3.2-6.1 which is
a non-maintainer upload. There was some drift as individual packages
were uploaded to get Sarge released. Hmm... That is going to cause
problems with my example above.

An 'upgrade' means packages must match exactly. If you have packages
A, B, and C installed and then 'upgrade' you will end up with exactly
A, B, and C installed after the upgrade. If package C depends upon a
new package D then the 'uprade' will not upgrade C and it will be held
back. The 'upgrade' cannot install a new package D. The list of
packages will be the same before and after when using 'upgrade'. This
means that A and B will be new but C will be the previous version.
This what I was referring to when I said it would be mixed versions.
But additionally I see now that it will be mixed versions anyway due
to NMUs and other things which are perfectly fine. Just mistaken
assumptions on my part.
A 'dist-upgrade' against a system with A, B, and C where C now depends
upon a new package D will allow the system to change the list of
installed packages. It will pull in D to meet the dependencies. Also
if D conflicts with some other package it will allow the other package
to be removed. Generally if you are tracking testing or unstable you
will always use dist-upgrade exclusively. Generally when tracking
stable and only getting security updates you will use upgrade
exclusively. But because they do slightly different things sometimes
you will use one or the other to achieve the desired effect.

Point to the new depot.
apt-get dist-upgrade
Or:
aptitude dist-upgrade
If that is clean then you have the full KDE available from the depot
on your system. Just note that as yet there may not be a full set of
packages in the new depot. KDE 3.4 is not yet released and is not yet
in sid/unstable. It is still experimental. As such it may not be
completely consistent. But most reports I have read are that it is
mostly working fine for people. YMMV.
