WordPress Chat breaks users profile with BB Friend Connections disabled

Hi all,

If i disable Friend Connections component in BP the chat plugin breaks php execution with the following exception.

[Sat Apr 26 17:57:28.795937 2014] [:error] [pid 2080] [client 79.50.54.126:56253] PHP Fatal error: Class 'BP_Friends_Friendship' not found in /var/www/sssa/wordpress/wp-content/plugins/wordpress-chat/lib/wpmudev_chat_buddypress.php on line 65, referer: http://localhost/members/

Enabling the component or disabling the chat plugin fix the issue.

Please help, i need to disable the FC component while using chat plugin!

Best regards
