Comment 47 for bug 312993

No, it is supposed to be document-cleanup. All icon names have been changed to follow the Icon Naming Specification, because originally I intended to use the themable app specific icons feature (see here: http://live.gnome.org/ThemableAppSpecificIcons), but this was reverted.

Please don't anything beyond fixing tango_icons.svg if you like, because how to implement this was hotly debated and we will revisit this after 0.47.
