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. today it happened again.

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.
