Zend Plugin found in view not in layout
===

I've got a plugin that retrieves a list of buttons.
When i call this plugin from the view (echo $this->GetAdminButtons()) it works fine.
But I need to call this plugin from the layout.phtml and when i do, the application just stops (white screen, no output)

When i try to get the exception message i get this error:

    Plugin by name 'GetAdminButtons' was not found in the registry;
    used paths: 
        Zend_View_Helper_Navigation_: Zend/View/Helper/Navigation/ 
        Zend_View_Helper_:            Zend/View/Helper/:./views/helpers/

Which confuses me because it works fine in the view .phtml files

Thanks in advance,
