[TYPO3] Toolbar in the Rich Text Editor??

[Bjarne HELLIGSOE]

I have been looking at the "Rich Text Editor" extension in the "Ext 
Manager". I found the follow text which was in red:

      Naming errors: classname 0 SC_rte_rte

                  1 SC_rte_cleaner

                  2 localFolderTree

                  3 SC_rte_select_image

                  4 SC_rte_user




Does that mean anything to anybody?
