I’ve got the same problem with duplicate group members. Since the group in question has 2 administrators I’m wondering if BOTH group admins received and accepted requests resulting in 2 instances of the same members in the group. There should be some test to see if a user is already a group member but that doesn’t seem to be the case. The link below is another example of the same issue. I’m running BP 1.2.3, WPMU 2.9.1 with subdomains.

If I don’t hear any possible causes/solutions, I’ll report this as a bug.
