I ran into this once recently, when I hit Ctrl-C at an inopportune
moment while yum was running on that window.  Like you, thought it was
the RPM database that was corrupt, and like you did the same thing to
no effect.

# yum clean all

had no effect either.

To resolve, I deleted all the contents of /var/lib/yum/.  It's kind of
heavyweight, but it resolved it.  You may try simply deleting
/var/lib/yum/history/* first, and see if that's sufficient (assuming
you don't need to be able to have yum roll back completed transactions
to some previous state).  If not, try deleting yumdb/ there.

There may be a better way to handle this, but I'll let the yum experts
chime in then.

Thanks,
Matt
