[expert] rpmdrake confused?

[Dan Swartzendruber]

this is really odd.  rpmdrake has suddenly developed amnesia about
my install cdroms.  i look at the list of packages available, and
select one.  i click on 'install/remove'.  it tells me to insert
the first cdrom (or the second, depending on the package).  i do.
i clock the ok bar.  it ejects the CD and says "try again".  is
there some kind of DB inconsistency issue here?
