Update:
Today I faced the problem again. Unfortunately I did not look into the .xsession-errors file before I started to relaunch kdesktop. Nevertheless it did not crash. First action: I started kdesktop from Konsole. It told me that kdesktop is already running but didn't come back to the prompt. Icons were not recreated. I had to Ctrl-C for the promt. "ps ax" showed me an old version of kdesktop and a second new one with <defunct> message. Killing the defunct one was not possible. I killed the original kdesktop program (Desktop went black) and relaunched it and - voila - the icons reapeared on the desktop. Also the defunct process of kdesktop was gone.

I do not find anything special in the xsession errors file. I try to investigate more accurate next time.
