Start live-usb-gui. Kdialog crash. I see in terminal:

kdialog(5709)/kdeui (kdelibs): Session bus not found 
To circumvent this problem try the following command (with Linux and bash) 
export $(dbus-launch) 
KCrash: Application 'kdialog' crashing...
KCrash: Attempting to start /usr/lib64/kde4/libexec/drkonqi from kdeinit
KCrash: Connect sock_file=/root/.kde4/socket-DELL-linux/kdeinit4__0

Impossible to report about bug to KDE4 via drKonqi: 
/Received unexpected error code 32 000 from bugzilla. Error message was: The
