BuddyPress.org

if you think you’ve found a bug in BuddyPress 1.2.7, and you’ve disabled all others plugins in an attempt to isolate the problem to BuddyPress (and tested on the BP-Default theme if possible), please make a report on http://trac.buddypress.org. You can use the same username and password that you do for this site.

If you can include clear, step-by-step instructions, it will make it more likely for a developer to confirm, test and fix the issue
