If this is reproducible, we need a valgrind log, or information about which kded module causes the crash. I fear this might be caused by the NotificationHelper. To debug kded4 issues, see http://kdepepo.wordpress.com/2011/05/11/troubleshooting-kded4-bugs/ For more information about valgrind, see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_with_Valgrind
To further investigate this issue, KDE developers need the information requested in comment #1. If you can provide it, or need help with finding that information, please add a comment.
