theme_item_list requires 'items' array in D7 in theme_fboauth_user_info();

This is pretty minor so I'm not bothering with a patch, but this:

$output .= theme('item_list', array('basic' => t('Your basic information (Name, Gender, Picture, etc.)')) + fboauth_user_connect_permissions());

should be:

$output .= theme('item_list', array('items' => array('basic' => t('Your basic information (Name, Gender, Picture, etc.)')) + fboauth_user_connect_permissions()));

in theme_fboauth_user_info() in fboauth.pages.inc
