There is not much art in svn art.
Assuming you are using svn trunk: Better to use the art from install, then copy data from install over data in trunk (but do not change data/gui). At the moment there are many problems with the new version of CS though, so a lot of things look bad, you will crash often (for example teleport does not work) etc. Also many things are under development, so GUI is not working well either.
