Open the file mentioned, and replace this:

$group_ids = $this->get_group_ids( $user_id );

with this:

$group_ids = BP_Groups_Member::get_group_ids( $user_id );

And right below that, replace this:

foreach ( $group_ids->groups as $group_id ) {

with this:

foreach ( $group_ids as $group_id ) {

That fixed the issue for me.
