Given that the kolab installation is behind an https-enforcing nginx proxy,
two things made this partially work:
1) /etc/roundcube/default.inc.php must have
   $config['use_https'] = true;
2) /etc/roundcube/kolab_filesinc.php must have:
   $config['kolab_files_url'] = 'https://' . $_SERVER['HTTP_HOST'] . '/chwala/';
   NOTE THE 'HTTPS'!

roundcube/chwale integration now works MOSTLY - the only thing that remains
broken is saving to cloud and attaching from cloud. No errors in the logs
again ... pointers?

Sincerely, joh
