Hello!

I'm updating my Umbraco Sites to 4.5.1 but somehow i face fatal server errors when trying to add a "TinyMCE v3 wysiwyg" (5e9b75ae-face-41c8-b47e-5f4b0fd82f83) to a media content type (Image to be specific).

I could reproduce the error on a fresh umbraco 4.5.1 installation by creating a new datatype, selecting "TinyMCE v3 wysiwyg" as Control, saving, setting some preferences (Ntext, some buttons, context menu, show label).
Then I opened the Media Type "Image" and added the Datatype. Opening any Image in the Media section results in:

Serverfehler in der Anwendung /.
