    <p>After installing and configuring the kolab objects ( contacts,
      agenda records ) can be created but not displayed.</p>
    <p><span style="color:#000000;background-color:#ffffff;">IN SQL we
        have   </span><span style="font-family:monospace"><span
          style="color:#000000;background-color:#ffffff;">2013110400.sql:ALTER
          TABLE `kolab_cache_contact` CHANGE `xml` `xml` LONGTEXT NOT
          NULL;</span></span></p>
    <p>But it seems the field xml is sometime null. This is valid for
      all cache tables.</p>

    <p>Another old problem in debian is<span
        style="font-family:monospace"> </span>the packaged php-sabre is
      old and incompatible with modern roundcube libcalendaring plugin.<br>
    </p>
    <p>I just run composer install in libcalendaring plugin and copied
      all content of vendor/sabre/vobject to
      /usr/share/php/Sabre/VObject <br>
