Class redeclaration error in frontend when upgrading TYPO3

Description
I upgraded TYPO3 from 6.2.17 to 6.2.23, cleared all caches from the Install tool. Then I get this error in frontend:
Cannot redeclare class TYPO3\CMS\Core\Utility\VersionNumberUtility in /home/xxx/www/typo3_src-6.2.23/typo3/sysext/core/Classes/Utility/VersionNumberUtility.php on line 21

Is this a bare installation without any 3rd party extensions? If there are extensions, can you check if one of them ships this class with the same namespace? For debugging purposes you can also use something like this to find out where that class was declared first.
Hi - we also got some problems with updating to 6.2.23 even after clearing all caches. Deleting (rm) the typo3temp folder completely and recreating the folder structure from the install tool helped.

Yes, this class is called by my versions of EXT:direct_mail, EXT:linkhandler and EXT:news.
Thanks to Birger: I let TYPO3 rebuild the complexe typo3temp/ structure, and that resolved this bug :)

Closing this issue as resolved. This was a cache issue.
