[wp-testers] DB warning on upgrade to 2.5 RC3

[Mark Heffernan]

Hi there,

Has anyone come across the below warning when upgrading from 2.5 RC2 to 2.5 RC3?

"WordPress database error Duplicate key name 'comment_approved' for
query ALTER TABLE wp_comments ADD KEY comment_approved
(comment_approved) made by dbdelta WordPress database error Duplicate
key name 'type_status_date' for query ALTER TABLE wp_posts ADD KEY
type_status_date (post_type,post_status,post_date,ID) made by dbdelta"

Error appears on link - /wp-admin/upgrade.php?step=1&backto=

Is this something to do with my server/DB setup, or a wordpress 2.5 RC3 issue?
I'm using Safari 3.1 on OS X 10.4.11.

Many thanks,

Mark :)
