[TYPO3-seminars] "Could not fetch page data for uid 0" after installation of seminars

[Jürgen Müller]

Hello, 

I have a problem regarding the seminars-extension in typo3
v.6.0. After installing the extension via Extension Manager, every time
I try to save anything or even activate/deactivate content/users in the
Backend, the following error occurs: 

"Could not fetch page data for
uid 0". 

The error is reproducable. After deactivation of seminars,
everything works fine. 

The stack-trace is the following:

Anybody got a clue, why this is happening and how it can be solved?

Thanks for your help!
