Version:            (using KDE 4.1.2)
OS:                Linux
Installed from:    Ubuntu Packages

after I upgraded my hardy to kde 4.1.2, after logging in to system, KDE crash handler says kded4 has crashed and have the following debugging output. I wanted too choose "kded" as the buggy package but it says this package does not exists in ubuntu!

Application: KDE Daemon (kded4), signal SIGABRT
