Weird duplicates in "rpm -qa" list

[kayvan]

I have a brand spanking new Fedora Core 4 system, yum updated to the latest.

While I was playing around, I noticed that some RPMs seem to be appearing twice in my list of installed RPMs:

[root@satyr2 ~]# rpm -q mikmod
mikmod-3.1.6-35.FC4
mikmod-3.1.6-35.FC4

[root@satyr2 ~]# rpm -q alchemist
alchemist-1.0.36-1
alchemist-1.0.36-1

What is going on here? Does anyone else see this sort of problem?

Do "rpm -qa | sort | less" to see this sort of thing easily on your system. Most RPMs will only appear once, but some are duplicated.

Any ideas?
