[kronolith] Kronolith not show icon in Horde/IMP

[Marcos Monge]

Hi all

I have installed Horde/imp/turba without problem (using mysql backend). 
It's working fine.
The authentication is delegated to IMP.

Now, I'm trying to install Kronolith 1.1.2. I configure it, using mysql, 
create tables, and all it's OK.
I activate in horde/config/registry.php (change the 'inactive' to 'active'),

If I go the kronolith URL directely  http://myohst/horde/kronolith, it 
work fine. I can put events, and all it's ok.
But, if I enter through the IMP, I can't see the "Kronolith/Calendar" 
button!!
I have checked all, and don't find the problem. The kronolith is 
activated in the horde/config/registry.php.

Anybody can help me?

My versions and configs:

Horde 2.2.5
Imp 3.2.3
Turba 1.2.2
Kronolith 1.1.2

Kronolith part in registry.php:
[.......]
/* events: Handler for events. */
$this->registry['events']['show'] = 'kronolith';
[.......]
$this->applications['kronolith'] = array(
    'fileroot' => dirname(__FILE__) . '/../kronolith',
    'webroot' => $this->applications['horde']['webroot'] . '/kronolith',
    'icon' => $this->applications['horde']['webroot'] . 
'/kronolith/graphics/kronolith.gif',
    'name' => _("Calendar"),
    'allow_guests' => false,
    'status' => 'active'
);
[.......]

Thanks in advance and greetings from Spain
