Javascript error when using RT editor

Deploy and start the Wiki30 project (it doesn't matter which DB).
Create a new page and start editing in RT mode.
The browser console displays the errors:

1) "NetworkError: 404 Not Found - http://localhost:8080/xwiki/bin/skin/skins/colibri/js/xwiki/editors/fullScreenEdit.css"
fullSc...dit.css
2) "NetworkError: 404 Not Found - http://localhost:8080/xwiki/bin/skin/skins/colibri/js/xwiki/editors/fullScreenEdit.js?language=en"
fullSc...uage=en

And the server console displays:
2011-11-08 11:00:05,451 http://localhost:8080/xwiki/bin/edit/Main/NewPage?&editor=rt WARN p.s.SkinFileExtensionPluginApi - Skin file extension with path [js/xwiki/editors/fullScreenEdit.css] is deprecated. Please use [uicomponents/widgets/fullScreen.css] instead.
