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.

today it happened again. Nothing special in .xsession-errors:
$ tail -n .xsession-errors

------------- snip ------------------
All errors are displayed more often before without the above described desktop problem (no icons, no middle and right mouse button menu).
Process kdesktop is running but there is additionally a "[kdesktop_lock] <defunct>" process. Might this be the culprit? I do not lock my desktop normally.
I can not kill the <defunct> process but killing kdesktop process and relaunching it restores all to normal.

now I have a running
21927 pts/4    S      0:00 kdesktop
21928 pts/4    S      0:00 /opt/trinity/bin/kdesktop_lock --internal 21927

process again.
