Bug#611272: Can't run KDE apps as root (Alt+F2)

[S D <sundimi@yahoo.com>]

Package: kdebase                         
Version: 5:66

Can't run KDE apps as root

To reproduce: Alt+F2, type Dolphin, then click on the "wrench" in the "Run Dolphin", then check "Run as a different user" checkbox, enter the username (root) and password. Dolphin starts seemingly with the same user's privileges instead of root's, no error message or other indication is given that something's wrong.

Thanks
