[CentOS] RPMDB problem

When doing yum operations I get this message at the end of whatever
yum was doing:

** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows:
brscan4-0.4.8-1.x86_64 is a duplicate with brscan4-0.4.3-1.x86_64

It is true, if I do "rpm -qa | grep brscan" it shows two of them.

what's the best/proper way to deal with this?
-remove both, reinstall one?
-remove one? which one? I don't see a feature in rpm (or yum) for
removing a single one of duplicate packages. How?

Thanks in advance!
