i have set up a test site with drupal 7.12 + media (7.x-1.0) + rotating banner (7.x-1.x-dev)+ style (7.x-2.0-alpha8) + Chaos tools (7.x-1.0-rc2)

and when i try to add a new rotating banner block title i get this error:
Call to undefined method stdClass::initialize() in C:\xampp\htdocs\test\sites\all\modules\rotating_banner\rotating_banner.classes.inc on line 279

I have tried the same installation with mysql for a database and it works ok.

I have also applied a patch http://drupal.org/files/issues/1160786-1.file_entity.patch and still no success.

Anyone out there has the same problems? Any possible solutions?
