same exact issue here. Same setup, in fact tried it on 4 complete virgin wp/bp installs today and all of them caused this error on trying to create/access a second group blog. It works for the first blog created, but none of the others work, they all produce this error.

I can also report that there is no extra info in the db tables, they are clean. Zero clue where to go from here.
