dpkg errors involving KDE3, libarts and kmail

[Oleg <oleg_inconnu@myrealbox.com>]

Hi

I use Debian 3.0 + KDE3 + X4.2 + OCaml 3.0.6 (see sources.list below)

When I do `apt-get update`, I get the following error:


Unpacking replacement libarts1 ...
dpkg: error processing /var/cache/apt/archives/libarts1_1.1.0-0woody4_i386.deb 
(--unpack):
 trying to overwrite `/usr/lib/libqtmcop.so.1.0.0', which is also in package 
libarts1-qt
dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:
 /var/cache/apt/archives/libarts1_1.1.0-0woody4_i386.deb


I've probably made a mistake when I did `apt-get install kmail` even though 
kmail was being "held back", but I thought I had to do it, because my 
original kmail didn't work (crashing when I hit "reply")

Many thanks in advance,
Oleg
