It is unusual that I use the root account, and I prefer to work under Konsole than under Dolphin when I need to perform certain root privileged task, so I did not realized till now the following:
When root's Dolphin runs under a user session, is almost unusable, but just to browser the directory tree or to make some basic file operations, such as copy, move, soft-link, because from it can not be launched Konsole (Tools > Terminal), or any command; open any file neither.
For instance, when clicked a text file, KDE complaints: "KDEInit cann't launch: <</usr/bin/kwrite>>."
Contextual menu operations, such as compress, &c., do not work neither.
Might you suggest me what else do you need (if any) to document this issue?

Reproducible: Always

Steps to Reproduce:
1.log in as user
2.launch Dolphin (superuser)
3.tray to open any document inside it, or launch Konsole, or compress, &c.
Actual Results:  
Dolphin is almost unusable, but just to browser the directory tree or to make some basic file operations, such as copy, move, soft-link.
From it can not be launched Konsole (Tools > Terminal), or any command; to open any file neither, to compress, &c.

Expected Results:  
Dolphin (as root under user login) be able to launch Konsole, Kwrite, &c., and compress, &c.
