After typing su, this happened both when I typed kdesu and when I tried to run a KDE application directly. This was previously reported with F17.... backtrace_rating: 4 Package: kde-runtime-drkonqi-4.9.5-2.fc18 OS Release: Fedora release 18 (Spherical Cow)
*** Bug 885688 has been marked as a duplicate of this bug. ***
You cannot run KDE apps under su (nor sudo), neither directly nor by running kdesu under su (or sudo). You need to run kdesu directly as your user instead. If you are seeing this crash (a qFatal("session bus not found");) when not running your application under su or sudo, your D-Bus must be seriously messed up.

KCrash: Attempting to start /usr/libexec/kde4/drkonqi from kdeinit sock_file=/root/.kde/socket-localhost.localdomain/kdeinit4__0 Warning: connect() failed: : No such file or directory KCrash: Attempting to start /usr/libexec/kde4/drkonqi directly I wonder why KDE is involved when using XFCE,
hp-setup is trying to run kdesu: > hp-setup[10145]: debug: kdesu -- hp-plugin -u --required --reason 1 To_install_plugin_for_HP_Device So I guess you should try running it as non-root, it will use kdesu to get root for the parts which need it. Or alternatively, try running "kdesu hp-setup" as non-root. I think HP designed hp-setup primarily for KDE, it is written in PyQt4, and as you can see, it uses kdesu for controlled privilege escalation.
