[Typo3-debian] Error message after trying to run site in typo3.6.0 (30-04-2004 final version) BACKOFFICE

[fabio.luedi at migrosbasel.ch]

Hi there
I just tried to update to Typo3 3.6.0 also, but got the same error. I even
cannot login. It's not so tragical since it's only a testing server, but
anyway.
Also I did enter the install-tool and so on, but same problem(s) afterwards.

So .. umm ... what's next to do if the other stuff failed?
