Warning while using WP-CLI

The remove page gets called on admin_init while it should be call on admin_menu, right?

When I hook it there the warning
PHP Warning: Invalid argument supplied for foreach() in /Users/jaime/projects/new-scientist/httpdocs/wp-admin/includes/plugin.php on line 1290 goes away.
