Yes I had this problem too. What I did is to use an absolute path in stead of ../library.

So this: ini_set('include_path', ini_get('include_path') . PATH_SEPARATOR . '../library/'); would become ini_set('include_path', ini_get('include_path') . PATH_SEPARATOR . getcwd() . '/../library/');

The problem I hink is somewhere in the savehandler because I had the exact same problem when I was using an sessionhandler.

Hope this helps.
