deleted this: com.apple.desktop.plist
then restarted and my icons in the folders appear to be back, as well as the icons on the desktop
When one newly downloaded beta app had no icon, I notified the developer. It turned out I was only person who'd reported this problem.
When a second newly downloaded released app had no icon, it was clearly time to figure out what was wrong with my fully updated 10.6.2 Mac. Google found this thread.
Deleting the com.apple.desktop.plist Preferences file, emptying the Trash, and Restarting restored the icons for both apps and a related license file. The only thing I lost was my desktop picture selection, which was easy to reset.
