In the loop when I print $registry->getApp() it is always 'horde'. So I made a 
test to return null when the app is horde. Then I get a PEAR error 
"permission_denied" though the variable $username given to the hook function 
is set. What I am doing wrong ?
Here is the code :

if (!function_exists('_prefs_hook_theme')) {
     function _prefs_hook_theme($username = null)
     {
	if (is_null($username)) {
             return null;
         }
	
	global $registry, $themeset;
	Horde::logMessage('hooktheme ' . $username,__FILE__, __LINE__, 
PEAR_LOG_DEBUG);
	Horde::logMessage('hooktheme ' . $registry->getApp(),__FILE__, __LINE__, 
PEAR_LOG_DEBUG);
	if($registry->getApp() == 'horde') {
	    return $themeset;
	}
	$themeset = $registry->call('vermeil/theme', $registry-
>call('vermeil/group'));
	Horde::logMessage('hooktheme ' . $themeset,__FILE__,__LINE__, 
PEAR_LOG_DEBUG);
	return $themeset;
     }
 }
