can't change Gnome icons' theme anymore

["H. S." <greatexcalibur@yahoo.com>]

In the new clean install of Debian Sarge (kernel 2.4.26), I can't change 
the icons'theme anymore in Gnome. When I do Applications->Desktop 
Preferences->Theme, I can change the windows theme, the border and 
controls but I can't change the icons theme. Be selecting different 
icons, nothing happens on the desktop.

Any suggestions?
