Using Chromium, Chrome and Firefox on Ubuntu I get the following error in the Console when trying to open the Admin Media Upload pages:
Error: The list field transformer with the key "icon" is not defined. You probably forgot to add it to the registry using the "add" method.

and after shortly showing the folders I get a blank white page and cannot proceed (uploading images).
