    Quick update: I've "fixed" the problem, but unfortunately my fix was to
    do a clean install again, this time formatting all the partitions
    except /home (previously, I didn't format my old /var partition). Right
    now, I'm in the process of restoring my old databases from backup and
    re-entering the privileges. So far, so good - no more Seg faults, and
    all my mysql_queries work fine.

    BTW, for those who are interested, I did open a bug-ticket with RedHat:
    https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=160691 . Maybe
    there's an easier fix, but I couldn't wait for it. Moral of the story?
    Maybe it's just always bite the bullet, and do a clean install when
    upgrading :)
