BuddyPress.org

I found a bug in buddyPress 1.2.4.1. When I try to create a new group with cyrillic name (“?????? ???” is “Hello world”, for example), i can’t create any topic for this group, because BP can’t insert a new record into wp_bb_forums table. And I always saw such message: “There was an error when creating the topic”.
But when I create a group with latin characters in its name, everything works fine, and I even can add posts and topics with cyrillic. Also, after creating a group I can rename it with cyrillic and this will not broke anything.

As a temporary solution I change group ‘name’ parameter, wich was $_POST with sanitize_title(esc_attr( $_POST)) in groups_create_group function. So I use slug instead of name.

Can somebody to advice me a better solution?
