Warning on group main page - Topic button?

I am working on a fresh install of a WPMU site with BP. I am not sure when the issue came up as I hadn't gone to the group pages for a bit but when you go a a groups main page there is a warning next to the request membership button. Seems like maybe another button (new topic) should be there?

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'bp_group_new_topic_button' was given in /home/crosseye/public_html/wp-includes/plugin.php on line 395

I can't post a link to see this as the site is not online at the moment. If a screenshot would help let me know and I can attach one. Thanks.
