For posterity:

The following setting of the Roundcube Sieverules plugin is relevant to 
solve this issue (from config.inc.php.dist):

// Sieve RFC says that we should use UTF-8 encoding for mailbox names,
// but some implementations does not covert UTF-8 to modified UTF-7.
// set to null for default behaviour
$rcmail_config['sieverules_folder_encoding'] = null; Setting it to 
'UTF-8' resolves the issue. Regards, Stephan.
