Back in Time as root - fails

My environment: Ubuntu 13.10, Gnome Shell 3.8.
Back in Time version 1.0.28
I want to run BIT as root.
When I click BIT (root) from dash it asks for password and then disappears.
When I submit 'gksu backintime-gnome' in terminal, I get the following:

josef@josef-amd:~$ gksu backintime-gnome
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 14: reading configurations from ~/.fonts.conf is deprecated.
Traceback (most recent call last):

Can you please help?
