Bleachbit with Root Privilege not Working on LOKI 0.4.1 - Need assistance. Please

Question

I'm Using elementary OS 0.4.1 Loki , in which the Bleachbit 1.12 with root privilege option is not working at all. App's icon just pops on the Plank Dock and Closes itself after some time. Nothing happens.

I tried using terminal by typing sudo bleachbit but this is what get

ABCD@xxxx:~$ sudo bleachbit
[sudo] password for xxxxxxxx: *********************             

(bleachbit:5756): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

(bleachbit:5756): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

(bleachbit:5756): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

(bleachbit:5756): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

After this bleachbit without root option window opens and that is running smoothly. This auto update option says that im in root privilege as in the picture. But options in Bleachbit are as same as normal not as root.

P.S I've also tried Bleachbit Beta 1.17 -------> SAME RESULT

For some reason, Loki doesn't come pre-installed with gksudo. When you launch BleachBit as root, it expects gksudo to be installed, so that it can prompt you for elevation.

In order to get this to work right, all you need to do is to install gksudo.

sudo apt install gksu

After executing this step, launching BleachBit as root should work fine.
