duplicate rpm packages

[J.L. Blom]

I hesitate a little as the problem is already mentioned in other forums
however without a real solution. But here is the problem.
In 64-bit systems by what reason several packages are visible in
duplicate in the rpm database. With a simple script which I will add
in-line in this message, all duplicate packages can be found (you can
also see them in e.g. webmin in the package list). They are not
different packages for different architectures but really duplications
in the rpm database. If you look it up (using e.g. webmin) the same
files in the same directories are displayed.
Using rpm -e is not possible as rpm won't remove it due to the fact that
it sees it as duplicate packages ( and assumes it is for different
architectures!):

rpm -e alsa-lib-1.0.13-32.fc5.at error: "alsa-lib-1.0.13-32.fc5.at"
specifies multiple packages

Does anybody perhaps have a solution?

PS: Here is the script (in a bad layout):

#!/bin/bash
rpm -qa --last >/tmp/timeorderedpackagelist ;olddupes=; allpackages=`rpm -qa --queryformat "%-30{NAME}\n" | sort`;
baddies="`q= ; for i in $allpackages ; do  if [ "$i" = "$q" ] ; then echo $i ; q=xxx ; else q=$i; fi ; done`";
baddiesnokernel=`echo "$baddies" | grep -v kernel | grep -v gpg-pubkey`;
for i in $baddiesnokernel ; do
    echo $i; grep ^"$i"-[0-9] /tmp/timeorderedpackagelist | cut -d' ' -f1 >/tmp/dupelist;  first=1;
    for j in `cat /tmp/dupelist` ; do
	if [ -z $first ] ; then olddupes="$olddupes $j";  fi;
			first=;  done  ;
    done ;
echo $olddupes;
