There are lots of new errors like this around and they have something to do 
with an update to PolicyKit.

Lots of people sudenly don't have permision to things like mount a usb drive 
or reboot.

With this comment I mean that maybe this is an unrelated problem to the one 
with the scanner.

Cheers!
