i try to make a bootable USB-Stick with USB-Creator but this fails permanently - also with root password.

- insert USB-Stick
- unmount it
- start usb-creator-gtk

- insert password
--> program opens up

- press "delete stick"
---> Error

In my case, I was getting this error because I didn't have a PolicyKit authentication agent running. Launching `/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1` before running usb-creator-gtk fixed this issue for me.
