This doesn't happen here, as in my /var/lib/dpkg/available is not
replaced with /var/cache/apt/available. You probably have some extra
software installed that keeps the two available files in sync. I
suggest checking your /etc/apt/apt.conf.d/* for something that syncs
the two and disabling that for a quick fix.

Thanks for the report. The conflicts is indeed verry odd. But if dpkg
is happy with it then I should be too.

Fixed in svn:

            version = "";


The problem should also go away if you comment out the squeeze entries
in sources.list or change the squeeze entries to deb [arch=amd64] ...
and run /usr/share/ia32-apt-get/convert-all-sources.list again. No
libmagick9 in sid packages.debian.org tells me.
