I tried downloading wpmu 2.7.0 and bp 1.0.1 – only the budypress activation returns error 500 in this case, the rest of the site continues to function.

Step 2 – install on server and verify it is working

Step 3 – Download latest version of BuddyPress (1.0.2)

Step 4 – copy to the plugins directory

Result
