bp_setup_current_user was called incorrectly

Hi,

in the debug log I get this message: "bp_setup_current_user was called incorrectly. The current user is being initialized without using $wp->init(). Please see Debugging in WordPress for more information. (This message was added in version 1.7.)"

in this location: "wp-includes/functions.php:3901"

and this call stack:
bp_setup_current_user()
wp-includes/functions.php:3901
do_action('set_current_user')
wp-includes/pluggable.php:47
wp_set_current_user()
wp-includes/user.php:2475
_wp_get_current_user()
wp-includes/pluggable.php:69
wp_get_current_user()
wp-content/plugins/wp-hummingbird/wp-hummingbird.php:253
get_current_user_info()
Unknown location
do_action('plugins_loaded')
wp-settings.php:277

Can you please fix this "bug".

Thx a lot,
Alex
