When trying to launch Kwrite in Konsole as root it crashes (OK as normal user)!  doesn't matter if it is just the application or trying to open a specific file. e.g.

[root@ASUS900 david]# kwrite
kdeinit4: preparing to launch /usr/lib/libkdeinit4_klauncher.so
kdeinit4: Communication error with launcher. Exiting!
KCrash: Application 'kwrite' crashing...
sock_file=/root/.kde4/socket-ASUS900/kdeinit4__0
Warning: connect() failed: : Connection refused
KCrash cannot reach kdeinit, launching directly.

[1]+  Stopped                 kwrite
[root@ASUS900 david]#

[root@ASUS900 lists]# kwrite bannedextensionlists
