[imp] Quota problem with Courier/vpopmail/qmail and latest horde/imp

[tapodufeu]

With the 3 last configurations, horde seems to works but impossible to 
see any maildir or the horde homepage. Only framework is visible.

In horde.log :
[Sat Feb 19 09:02:27 2005] [error] PHP Notice:  Undefined index:  params 
in /var/www/horde/imp/lib/Block/summary.php on line 57
[Sat Feb 19 09:02:39 2005] [error] PHP Notice:  Undefined index:  params 
in /var/www/horde/imp/mailbox.php on line 392

Summary.php on line 57
$quotaDriver = 
&IMP_Quota::singleton($_SESSION['imp']['quota']['driver'], 
$_SESSION['imp']['quota']['params']);

mailbox.php on line 392
     $quotaDriver = &IMP_Quota::singleton($imp['quota']['driver'], 
$imp['quota']['params']);


So even if if configure params for quota in servers.php, these scripts 
don't work.


Do you have any idea about my error or misconfiguration ?
Any example of configuration for my simple case ?


Thanks for all,
Aldric
