Bleah! I see mis-matched db3 and db4 calls mentioned there... You didn't
upgrade rpm to the Fedora 10 version, did you? Historically, rpm has
used its own internal copy of berkeleydb, which I believe was db3, but
in F10, its switching to the system-provided db4.x.

Hopefully, this should do the trick:

1) rm -f /var/lib/rpm/__db.*
2) rpmdb --rebuilddb
