this looks like trouble. I'd say you should uninstall and reinstall
your database-related Perl modules. There may be a library mismatch or
similar problem, which may be very tricky to track down.

If suexec is in use for Bugzilla,
http://groups.google.com/group/mozil...c3c837c65edcce
might be of interest to you.

This is https://bugzilla.mozilla.org/show_bug.cgi?id=380077. Check
whether disabling SELinux helps. If it does, re-enable it and
configure it so that it allows Bugzilla to read data/params. (I have
no idea how to do this.)

Kind regards
