TYPO3 Core

The BE-Login with Typo3 Version 6.2.4 sometimes throws an exception:

#1: PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: Function spl_autoload_call() hasn't defined the class it was called for in ***/typo3_src-6.2.4/typo3/sysext/backend/Classes/Controller/LoginController.php line 147 (More information)

This happens mainly when I don't log out from the backend and then open the browser on the next day, so I guess the session just has timed out. I also saw that there are 2 cookies set: PHPSESSID and be_typo_user - when I delete these cookies, the backend login works again until the next day (when I reopen the browser and the session propably has expired).

Here is the full stacktrace as shown by the excpetion:
