[TYPO3] beta3 / TV 0.5.0: BE User can't create new content elements

[Peter Kraume]

Hi all,

I'm currently using the Beta 3 together with Templa Voila 0.5.0.
My backend users who are not admin, are not able to create new content 
elements with TV. After picking the type of the content element, they 
always end up with an error message about insufficent rights. Editing an 
existing content element is no problem.
And if the user has admin rights, there is also no problem.

Any ideas?

Thx
Peter
