Confirmed that as of Linux Mint 18.1 (Mintstick v1.3.1) this still fails. Mintstick (USB Image Writer) should be requesting root privileges, and is not doing so.
Interestingly, if I run mintstick from the command-line as "sudo mintstick -m iso ISO_NAME.iso /dev/sdX" it will bring up the GUI for the command, but will not fill in the values passed to it.
