After deleting some old contacts these contacts are still shown in Krunner and the 'contacts menu in the 'Search and Launch' activity. The problem only occurs with old contacts. When I add a new contact, the contact is shown by the plugin and after deleting this contact, it's not shown any more. I've installed - KDE 4.8.3 - nepomuk 4.8.3 - akonadi-server 1.7.2
I've exported the akonadi database to a text file with mysqldump and searched for the deleted contacts in this text file without success.
I've found a solution: I deinstalled kaddressbook. After that I removed all folders and files which still contains some references to kabc. rm -r $HOME/.kde4/share/apps/kabc rm -r $HOME/.kde4/share/apps/nepomuk/ rm -r $HOME/.kde4/share/apps/kconf_update/ rm $HOME/.kde4/share/config/krunnerrc rm $HOME/.kde4/share/config/kglobalshortcutsrc rm $HOME/.kde4/share/config/plasma-desktoprc rm $HOME/.kde4/share/config/kdebugrc rm $HOME/.kde4/share/config/kbookmarkrc
