I'm running Kubuntu 12.04 with KDE 4.11.1 and the rootactions service menu in Dolphin.
I opened Dolphin as root then clicked on a text file. I got a "Sorry" dialog with the message:
KDEInit could not launch /usr/bin/kate
So I opened a terminal and issued this command as root:
That worked and Kate opened as expected.
Why is Dolphin giving this error and how can I fix it? Thanks.
