[CACHE] Post-Install issue in admin/settings

On some hosts, with {some} cache installed,

installation goes through OK as cache is set as 'filecache' install/install.php::113

define('CACHE_TYPE','filecache');

but on 1st login to admin panel,

Scenario:

go to Settings
just click on 'Save Settings'
blam... Blank page,

as cache has just been set to 'auto'

and depending on the host, a non-file cache as been selected but now that cache needs params to be used... (ex: Memcache needs to connect to a server, etc...)

Critical sections

includes/bootstrap.php::30-31

//start cache
Cache::get_instance(CACHE_TYPE,CACHE_EXPIRE,CACHE_DATA_FILE);

includes/classes/cache.php::292

public function set_cache_type($type)
(...)
        case 'auto'://try to auto select a cache system
            if     (function_exists('eaccelerator_get'))$this->cache_type = 'eaccelerator';                                       
            elseif (function_exists('apc_fetch'))       $this->cache_type = 'apc' ;                                     
            elseif (function_exists('xcache_get'))      $this->cache_type = 'xcache' ;                                        
            elseif (class_exists('Memcache'))           $this->init_memcache();
            elseif (class_exists('fileCache'))          $this->init_filecache();
            else $this->cache_error('not any compatible cache was found');
        break;

Workarounds

public function set_cache_type($type)

// change order of the auto select

// put if (class_exists('fileCache')) $this->init_filecache() FIRST

++++++++++++++++++++++++++++++++++++ Possible ENHANCEMENT:

auto fallback to fileCache
includes/bootstrap.php::30-31

//start cache
if (CACHE_ACTIVE===TRUE)  Cache::get_instance(CACHE_TYPE,CACHE_EXPIRE,CACHE_DATA_FILE);

++++++++++++++++++++++++++++++++++++ IMPORTANT:
