[TYPO3-templavoila] Fatal Error: Cannot use string offset as an array

[Thomas König]

Hi List,
i just installed Typo3 4.0beta3 and Templavoila 0.6 on my server.
I then used the tv-wizard to create a site and that worked fine.
But then i was trying to create a new Template Object (if i remember 
correctly) and now i get the following error when i go to the "Storage 
Folder" in my new Site (in the templavoila module):

Fatal error: Cannot use string offset as an array in 
C:\wamp\www\typo3_4\typo3conf\ext\templavoila\mod2\index.php on line 1314

I got PHP 5.1.2 installed so it might be a problem with php5? (after 
googling the error message...)

Is there any quick fix/help for that?
And is there a templavoila bugbase?

Best regards,
Thomas
