Problem with horde/lib/Auth.ph (unserialize)

[jvandal@subi.to]

Hi,

I use Horde (3.0-cvs) and IMP (4.0-cvs) (Redhat 7.2) and a few time when I log 
on IMP, the following message appear on top of summary page...

---
Warning: unserialize() failed at offset 0 of 36 bytes 
in /var/www/html/horde/lib/Auth.php on line 234
--- (3 times)

I'm new to PHP and I don't know if the following change can cause other problem 
but this solve my problem...

horde/lib/Auth.php ... function getCredential($credential)

234c234
<             $credentials = unserialize(Secret::read(Secret::getKey('auth'), 
$GLOBALS['HTTP_SESSION_VARS']['__auth']['credentials']));
---
>             $credentials = @unserialize(Secret::read(Secret::getKey('auth'), 
$GLOBALS['HTTP_SESSION_VARS']['__auth']['credentials']));
