Bug or no bug, this is the question

Hi dear maintainers, 

when I am updating my system, I sometimes get these errors:

--------- snip -------

protheus2:/var/cache/apt/archives# LANG=C dpkg -i libc6-i386_2.6-1_amd64.deb
(Reading database ... 234520 files and directories currently installed.)
Preparing to replace libc6-i386 2.5-11 (using libc6-i386_2.6-1_amd64.deb) ...
Unpacking replacement libc6-i386 ...
dpkg: error processing libc6-i386_2.6-1_amd64.deb (--install):
 trying to overwrite `/usr/lib32', which is also in package lib32z1
Errors were encountered while processing:
 libc6-i386_2.6-1_amd64.deb

-------- snap -----

O.k., there are some files, who want to be overwritten, and yes, the package 
can be installed with the --force-overwrite option.

So, is this a real bug, which should be reported ? I found no option when 
using apt to get such a package installed. So I use dpkg.

Anyway, this behaviour appears sometimes, and yes, I am running sid.

Thanks for your help.

Regards

Hans
