[ingo] Ingo unable to write new rules - 2

[Marie Camps]

Hi,

I have the same problem as Chris with the new version of ingo(ingo-3.0.0beta1).

when a user tries to save a new filter, the following message appears:
Script not updated: There was an error activating the script. The driver said: 
Unable to write VFS file ".procmailrc".

the file backends.local.php is configured as follow:

$backends['procmail'] = array(
    'disabled' => false,
    'transport' => 'vfs',
    'hordeauth' =>  true,
    'params' => array(
        'hostspec' => 'localhost',
        'filename' => '.procmailrc',
        'vfstype' => 'ssh2',
        'port' => 20000,
    ),
'script' => 'procmail',
    'scriptparams' => array(
        'path_style' => 'mbox',
        'variables' => array(
                'PATH' => '/usr/bin:/usr/local/bin:/bin',
                'LOGFILE' => '$HOME/procmail.log',
            'VACATION_DIR' => '$HOME',
        )
    ),
    'shares' => false
);


And the horde log show:
2012-09-25T11:31:22-03:00 NOTICE: HORDE [ingo] PHP ERROR: Undefined index: 
vfsroot [pid 23062 on line 748 of "/usr/share/php/Horde/Vfs/Ssh2.php"]
2012-09-25T11:31:22-03:00 NOTICE: HORDE [ingo] PHP ERROR: Undefined index: 
vfsroot [pid 23062 on line 748 of "/usr/share/php/Horde/Vfs/Ssh2.php"]


The PECL/ssh2 is working .


Could anyone help us?


Thank in advance!
