When deleting the last item under [Media] in the backend (tested with folder), the page is empty (there should be a listing on the left). When trying to create a new folder without reloading the page, a "You don't have permission..." error message occurs.
Workaround: Refresh page (click on [Media] again).
Fixed. I also added a dialog asking for folder name when clicking on "New folder". If no folder name is given, "New folder" (or translation) is used. (Old behaviour.)
