Version: (using KDE 4.3.0) OS: Linux Installed from: Ubuntu Packages Running kate with sudo wreck havoc with permissions in temporary files in /tmp and /var/tmp I know have a lot of warning such as the one following when apt-get installing konversation or any kde app which require post-installation configuration. Error: "/tmp/kde-fredf6" is owned by uid 1000 instead of uid 0. kdeinit4: preparing to launch /usr/lib/libkdeinit4_kbuildsycoca4.so <unknown program name>(14463)/ KStartupInfo::createNewStartupId: creating: "fredb;1251896402;815342;14463_TIME0" : "unnamed app" kdeinit4: preparing to launch /usr/lib/libkdeinit4_kbuildsycoca4.so <unknown program name>(14499)/ KStartupInfo::createNewStartupId: creating: "fredb;1251896402;815866;14499_TIME0" : "unnamed app" kbuildsycoca4 running... kbuildsycoca4 running...

That is a generic problem, if any, I would not start Kate or any other KDE application as root.
