Version: 0.12.1-1 I can confirm this problem also exists on Debian Wheezy in KDE 4.8.4.. When I select "gparted" from the KDE menu, the "busy" cursor appears but gparted fails to start. When I go into the menu editor, find gparted, and select "run as different user", save, and then try running it again... KDE then prompts for the root password and runs gparted properly...
Please fix the menu item for gparted so it works by default.
