Upgrading "system/database" folder breaks my application

I sit corrected. It's the function named _protect_identifiers() in ./system/database/DB_driver.php that's the problem. It's explodes by the dots, instead of splitting by . and =.

EDIT: Correction, I don't think that's the problem, but the problem is definitely within this function for sure.
