Redis Cache Problem

Using CI rc3 and redis (v3rc5) I am having trouble with the caching.

I can set key in the cache and read it fine until it's TTL has expired. Then it will miss and not save anything to that key anymore.

I have to go into redis and manually delete the '_ci_redis_serialized' key for it to work again.

If i change it to use file cacheing it works fine.

Has anyone else noticed this problem or is it something I am doing wrong?

PHP Code:

$this->load->driver('cache', array('adapter' => 'redis')); // in __construct()

if (! $cache = $this->cache->get('allNews') ) {
      $query = $this->db->get('news');
      $result = $query->result_array();
      $this->cache->save('allNews', $result, 10);
      return $result;
} else {
     return $cache;
}

I actually found a fix. There's a flaw in the logic in the save() function in the caching engine.

I'm preparing a pull request, its my first one on github so we'll see if it works.
