Application: kcminit ()
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.3
Operating System: Linux 2.6.37.6-0.5-desktop i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
After manually bein forced to kill DBus-dameon since it was at 100% CPU and
blocking everything else to be launched in KDE a number of problems terted to
appear. Even aftar a relaunch of Dbus things did not work and forces a restart
of KDE to get back to normal. 

One thing unusual before this crash was that the HP-printer systray had Python
hung at 100% 

Then after killing the systray for HP printer I received this crash.
