Some cache backend adapters does not require options. When i tried set a template from .ini file a unexpected behavior happens

i've put this in my .ini file

resources.cachemanager.something.frontend.name = Core resources.cachemanager.something.frontend.options.lifetime = 7200 resources.cachemanager.something.frontend.options.automatic_serialization = true resources.cachemanager.something.backend.name = Apc

after i try do this

$cache = $bootstrap->cachemanager->getCache('something');

Expected result

$cache instanceof Zend_Cache_Core; // true

Actual Result

PHP error: Zend_Cache_Backend_Apc::__construct() expects array, null given

i've tried this resources.cachemanager.something.backend.options[] = but not work as well, because this is translated to array(0 => '') so i got Zend_Cache_Exception "Incorrect option name : 0"

It doesn't happens when some option for cache_backend is configured

Possible Solution

when a new template is setted in Zend_Cache_Manager::setCacheTemplate() it may check 'options' index and create this one as a empty array (for both side, frontend and backend)
