Bug 251189

Application: kded4 ($Id: kded.cpp 1156841 2010-07-29 19:59:05Z zander $)
KDE Platform Version: 4.5.1 (KDE 4.5.1) "release 3"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.4-11-desktop i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:

After the Login KDED crash. I tray to start in manualy and get this output:
QDBusObjectPath: invalid path ""
KCrash: Attempting to start /usr/bin/kded4 from kdeinit
sock_file=/home/johann/.kde4/socket-andrea_j/kdeinit4__0
KCrash: Application 'kded4' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/home/johann/.kde4/socket-andrea_j/kdeinit4__0
kded(7610): Communication problem with  "kded" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "

run kded4 --check seems to fix the triger of the bug
kded still report a lot of problems:
