"Error: Could not parse xhtml office content." on importing Office Document

I am receiving "Could not parse xhtml office content." on importing a new doc via Import feature from WYSIWYG editor or via Add Page from Office Document. So all I do is basically choose the file, set it to filter the styles and then upload it. In WYSIWYG I am even shown a proper looking Import but I can not get to the wiki code and previewing or saving fails. The server log shows something like this:
