as mentioned in #22; I had this issue when I messed up accounts and groups. It prompts (with an ugly prompt) for authentication if you're not in the lpadmin group. When I set 'sudo usermod -aG lpadmin myusername' it worked flawlessly afterwards.
The bug is that it does not detect more gracefully if you are not a member of the lpadmin group.
