i tried to install some icon-themes from: http://art.gnome.org/themes/icon/index.php using the preferences->theme-application. it installs them, but they don't show-up in the resp. icon-submenue. i also tried to install the svg-extra-themes, but this also didn't work. i already had the same problems with rh9. if someone could give me a hint, i would be very happy! thx.
