error on upgrade to 2.5.1

I received the following error after clicking the upgrade link. I went from 2.5 to 2.5.1, it seems to have worked properly but figured I would check to make sure it isn’t an issue:

[Mon Apr 28 14:43:37 2008] [error] [client IPADDR] WordPress database error Duplicate key name ‘comment_approved’ for query ALTER TABLE wp_comments ADD KEY comment_approved (comment_approved) made by dbDelta, referer: https://www.SITENAME.net/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F
[Mon Apr 28 14:43:37 2008] [error] [client IPADDR] 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, referer: https://www.SITENAME.net/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F

Any ideas?
