DCOPserver error during KDE login

Yesterday my laptop ran out of power and during the emergency shutdown stuff got apparently screwed up. When I tried to log into KDE this morning, I got the following error message: There was an arror setting up inter-process communication for KDE /home/jeltsch/.DCOPserver_michael-laptop__0 could not read network connection list Please check that "dcopserver" is running This is again a very non-informative error message. The way to fix this was as follows: rm ~/.kde/socket-michael-laptop rm ~/.kde/tmp-michael-laptop rm -rf /tmp/kdesocket-jeltsch rm -rf /tmp/kde-jeltsch There were errors while removing the directories in /tmp. Even as root I couldn't remove the directories; the error message claimed they were not empty. But there were no files when listed with ls -al. As a workaround a renamed the directories: mv /tmp/kdesocket-jeltsch /tmp/kdesocket-jeltsch.old mv /tmp/kde-jeltsch /tmp/kde-jeltsch.old After this I could again log in, but the items from my Panel had disappeared.
