It sounds a bit odd that you are having trouble when logged in as root. If you log in to the Window Manager as root than you would be running GUI applications as root and should have no trouble.
You can check the permissions with
ls -al /usr/share/themes
You should see all files have owner root and permissions drwxr-xr-x which means they are writeable by root but not by any other user. The top directory also has the same permissions.
If you are logged in as a normal user, then you could try launching the extractor utility using sudo
Did you see the discussion on Ubuntu forums about this?
They could have some useful hints.
