[Plugin: Capability Manager] Error on listing capabilities

I have installed the plugin, on displaying the capabilities for a user (wp-admin/users.php?page=capsman) i got for each cpbility the error :
Notice: Undefined index: create_users in /users/gstrey/www/wp-content/plugins/capsman/includes/admin.php on line 75
/>
As I am in a plugin development i have defined the DEBUG constant to true to show all errors
