Dear Maintainer,


   * What led up to the situation?
   
     Launched system-config-printer as a regular user and attempted 
     unlock dialog to add new printer to system.

     Using XFCE desktop

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

     Closed dialog and ran system-config-printer from terminal and
     repeated steps.

     
   * What was the outcome of this action?

   The following error was thrown:

   Gtk-WARNING **: 08:47:30.475: Error acquiring permission: Failed to acquire permission for action-id org.opensuse.cupspkhelper.mechanism.all-edit

   * What outcome did you expect instead?

   elevated permissions dialog

   * Workaround

   running sudo system-config-printer from the terminal provides for
   normal operation

   * Additional information

   found similar bug from Fedora 26 that was resolved by installing
   policykit-1-gnome. This did not correct the issue.
