Re: RC-1: no widgets?
Sadly, i must confirm this issue with a german BP RC1, too … 
Exactly the same problem as sgrunt declared.
The only workaround to handle/ display widgets again seems to be deleting the wp-content/mu-plugins/bp-languages/buddypress-de_DE.mo (or what language ever).
Praying for this issue being solved soon, since I had planed to launch my BP-Site “officially” this weekend …
