[opensuse-factory] Kate / Kwrite does not launch from Dolphin started in SuperUser mode

When dolphin is started in super user mode, it not possible to launch kate or kwrite. When a text file is highlighted and with a right click kate / kwrite is selected (as editor), there is no response. Leafpad and gedit work fine. In a console, "sudo kate" does not work. There is a message SUDO_EDITOR=kate sudoedit <file>". This is annoying as I like to use kate / kwrite to edit files as root when necessary. Is there a work around? Regards -- Sudhir Anand
