The package system still knows that the file should be there, therefore
it will refuse to install. It is normally better not to move around
system files unless you really know what you are doing.

Where does this "bonjour" package come from? I can't find it in any of
the official Debian branches. It is probably the root of the problem. To
get rid of it you can proceed as follows:

1) Install libavahi-compat-libdnssd1 by brute force and let it overwrite
   the file:

   dpkg --force-all -i /var/cache/apt/archives/libavahi-compat-libdnssd1_0.6.9-8+b1_i386.deb

2) apt-get install -f

3) apt-get remove bonjour
 
4) apt-get --reinstall install libavahi-compat-libdnssd1

   (Just to be on the safe side; this is probably not necessary, but you
   never know...)

5) apt-get install kde

   (or something else, depending on what is missing)
