Disabled add-buttons in addressbook

[nilu]

I cannot add and delete contacts in my addressbook because the add- and delete-buttons are disabled.
But adding a contact by clicking "+" next to an e-mail-address in an email works.

Investigation:

I have

$rcmail_config['ldap_public'] = false;

in my config/main.inc.php.

In steps/addressbook/func.inc line 56 the foreach-statement sets the address-source to readonly because:

(array)$CONFIG['ldap_public'] 

is converted to an array with on element:

echo var_dump((array)$CONFIG['ldap_public']);

array(1) { [0]=> bool(false) }

Possible Fix:

Add an additional check (steps/addressbook/func.inc Line 56):

if($CONFIG['ldap_public'] != false){
  foreach ((array)$CONFIG['ldap_public'] as $id => $prop)
